I'd love a Stormtrooper landing shuttle, like in the background of ANH. Also, a properly scaled Y-Wing and Skiff would be awesome.
I'd also like a rerelease of the 2010 snowspeeder in other Rogue colors. The one we have is Luke's, and it doesn't have the squad markings. Hell, I'd just like to get a few more of them.
How is the scale on the B-Wing? I was watching ROTJ the other day, and it didn't look too far off, but I couldn't be sure. That's a ship I'd like to see return in one of the movies. Didn't get enough screen time, IMO.
