Well, since everyone else has done (p)reviews, I figure I'll do one, especially in light of the new pic with which the magazine has provided us, better in quality than the leaked pics, even! (Greg was right! )
I'll start with the Nuva, since I want to get this started on a good note.
Lewa Nuva-- Lewa Nuva was initially that which I liked least. Now, with new and better pics available, that role has been passed to Kopaka. The new Miru Nuva, some might argue, is vastly different than the old one. Not so, say I. Though the spikes are not present aside from a finlike one on the top, there are other similarities which include the two cheek-boxes on the sides (now in propellor flavors!) and the overall shape of the mouth. Yes, I made an edit to prove it.
As for the rest of Lewa's construction, let me begin by stating that I don't like his sword all that much, though I will not deny that it is suited to him. The reason I don't like it is a matter of function-- no practical pistons, no apparent joints, no evident function whatsoever from the pics with which we have been provided. However, I must say this is just a bad direction LEGO seemed to take with the Mahri, and perhaps one I will grow to love. The jet on the back brings relief in that it has implied pistons and that yes, they appear practical!
People complain that the torso construction is boring, but as I have pointed out in the past, normal Toa torso constructions have varied more in this story book than ever before, and at least the Inika torso piece has been shown to be useable in other sets (more than can be said than ANY other Toa torso piece in the past). The practical pistons on the Nuparu Inika chest armor are also a plus. His feet and legs are a bit disappointing, though the feet will grow on me and I can't complain about the use of Inika thigh armor-- possibly the best armor suited to the Nuva. More on that later.
Pohatu Nuva-- Pohatu Nuva initially was a bit upsetting-- some of the ideas I'd seen in "OMG brown is gone!1!11!!" topics had been semi-reasonable, the best being the idea of using Keetorange and Avak brown in conjunction. However, I think the more subdued color scheme used here actually seems better-suited to Pohatu, and as I have said since the start we at least won't have to hear all that cool dudic (for the word I would like to use is censored, and this evokes the same meaning in use of the same suffix) whining about how "yellow rocks don't exist! yellow sand doesn't exist!" Anyway, I've grown to like this new color scheme (and anyone who says orange is a fire color should tell that to the makers of all those Nuparu revamps).
Pohatu's mask, while it bears a less obvious resemblance to the older form, still has a few minor similarities, and more importantly a look well-suited to Pohatu. And LEGO knew what they were thinking by making it Vahilike in both color and shape-- whether or not people like the mask, people will buy it in order to get their hands on "the new vahi." (sorry, no edits until I can get my hands on a pic both large and non-leaked).
As for his torso, I applaud it. It gives Pohatu that beefy look that works so well for him, though I would have preferred if his shoulders were attached in the exact same way as Kongu's (they are too flat as-is). His leg and arm armor is not the ideal armor I mentioned before, it is necessary to keep him from looking lanky as opposed to beefy. Feet and armor choice also helps to provide stylistic consistency with his mask.
The drills/propellors are probably the best tools for early '08, though I can't see any pistons that appear practical. Thus is the dreadful result of function and poseability-- practical pistons are lost each time such a change is made. Still, without the function, these tools would be rather pathetic, so I'll get over it.
Kopaka Nuva-- Mask equates to disappointment. I love the lightsaber blade eyepiece-- it works well with Kopaka-- and will get over the switching of the eyepiece in time, though it will make an awkward transition present in my drawings of Kopaka. Also, it is ridiculous to say that it looks too much like Whenua's mask-- by that logic, the Kaukau Nuva looked too much like the Hau, as did the Avohkii. My main problem with it is a shameful bias-- I hated the Akaku Nuva in the first place.
Wings are good. I don't care that they look like airplane wings; I think airplane wings are much better than angel wings or FINS (THEY'RE NOT WINGS!!!!) for a Toa of Ice.
The bayonet is a plus-- while I mourn the loss of his sword and shield, this seems just as well-suited to Kopaka's icy personality. Plus, it gives some much-needed variation to the skyblaster. No practical pistons, sadly.
The torso seems cliche at first glance, but from various pics I have ascertained that these torsos are more than they appear (they have to be to make the piggyback feature possible and simple). Leg, arm, and foot armor is also good, though it is beginning to appear said armor is not light bley as I so earnestly hoped.
Overall-- Midak Skyblaster is a beautiful weapon, and one that will be thankfully easy to draw with some minor stylization. It also looks promising in terms of function. Color schemes look promising for these Toa, though I should hope they will not become standard-- I was liking the variation in sets as of late. Torsos are as much as we could have expected based on precedent. I sat that overall, these new Nuva get an 8/10 (mostly brought down by Kopaka). That is apt to change once better pics (or even better, the sets themselves) become available.
