I think a fresh start is most likely - a continuation while it could work, I think would require a lot more work for them to balance having the prior history, whilst not making it too inaccessible for the newer audience. That being said if you're going to revive a line with such a history, you'll definitely want to reference its history here and there - so in that case it would be a continuation. Practically thinking though what I imagine it to be would be a reboot. Second question is hard to say - I think the best indicator of what a new Bionicle line would be like would be the current Chima line. I really like a lot of the sets, but unfortunately don't know too much about the story.From what I have seen though I think the lore is pretty good but not as good as Bionicle's (even the early days where it wasn't as extensive - a fairer comparison I think since the Chima line hasn't been around as long). I'd have high hopes - but it'd be very hard to exceed the heights of the original.
