Star Wars - Bring on Rouge One and the return of Vader :)
Bionicle - It seems my interest of Bionicle has steeply lapsed over the past year and I only managed to get my hands on Tahu and Tahu alone. I wonder if it is worth getting the rest at this point or just go for the new wave of Toa
Metal Gear - Is Metal Gear Survive the final nail on the coffin for the series? I guess we'll have to wait and find out.
Halo - I'm really enjoying the post release support for Halo 5 that 343i have given the fans. Some can argue a couple of things hurt the community like micro transactions but the good outweighs the bad!
...More to be added when I think of something else.
