Totally forgot about the Gunship....good choice there. I could see them re-doing and upscaling the Gunship, and...as mentioned...with the crossover with CW it would be a really nice choice. You can fill it full of clones, pack in some lights and sounds and lots of launchin' stuff. That would be a nice vehicle. I hope we do see that one. All the other choices sound pretty good to me too. I'd really like to see some sort of Death Star, even if it is underscaled and all that (because we know it will be). Just having a nice, fun playset like that would be cool though - I always wanted the vinty one.
It does show that we've had a decent run of large vehicles though, because it is tougher to think of good choices here and there. Honestly, a lot of it has been covered pretty well, which is nice. I wouldn't mind seeing upscaling of some other previously made ships too (or instead, if there isn't a good "big" candidate), like the already mentioned Gunship, or an all-new X-Wing or Y-Wing for the OT.
