For the vehicle issue...
I'm not sure what to make of what's listed. I half expect the TIE Fighter and X-Wing to be the Vader TIE and Red Leader ships... And a Falcon will just be something we've yet to see. I could be wrong of course, but ALL those ships in a single year? Seems fishy to me is all.
I'd take LOTS of things resculpted though...
-To-scale AT-ST... This easily tops my list, and if they ever did this I'd be in line to buy a half dozen of them. No walking feature, just poseable legs. Cockpit built for two (or two ewoks and a wookie)... Could be a very nice item, though one I'm not personally expecting. Oh, and opening window armor would be kinda neat too.
-To-Scale Snowspeeder... I'd LOVE to see this one done to the proper size for the action figures. Include a Generic Dak (with removable helmet) type of pilot this time, and I'd dig it even more, but even without figures this is easily my 2nd most requested item.
-To-Scale Speederbike w/super articulated scout... I'd take this in a heartbeat, and I think others would as well. I'd be lining up to buy this one too, and in droves. If for no other reason than simply to get an army of nice SA scouts.
-To-Scale TIE Fighter... They're close... Just need to fix the panels at this stage since they have the proper cockpit mold now. Again I'd buy this one in multiples.
-To-Scale Tatooine Skiff... Lower on my list, but the original is a bit undersized so I'd take a newly detailed and sized one. With the new Skiff Lando, I can just imagine him hanging off of a new skiff.
Beyond that, I'm not sure of anything that I'd consider "reasonable" to expect from Hasbro at this point... I mean, I want the age-old "Modular Millenium Falcon" done to have a full scale Falcon but I just don't see them ever bothering with it... I want a full scale Sail Barge (Not as big as people think), but just can't imagine it being done. Lots of play value with a vehicle like that, and it's really more a playset than a ship, but I'd love one either way...
The ships I listed are the only things I'm expecting them to ever retool really. Possibly a Y-Wing... I'd like that if it were to-scale too, but the Y-Wing seems to be an area Hasbro doesn't wanna get too close to.
It'd be nice to see all the fighters redone personally, and done larger, but I can just imagine the uproar everyone would have who bought the X-Wings they've put out already. I'm just tired of my A-Wings almost being as big as all the other ships.

Anyway, I'd take some of the ones I listed though for sure... To me, they're the most absurd looking vehicles in the line when compared to other newer vehicles, or even the detail put into the figures. Things like the AT-ST and such just look bad in comparison.
