Put me in the list of people that thinks the Geonosian Fighter could stand to be reissued. I have one, and it does indeed suffer from a very slight drooping of the noses (as scockery mentioned), but it's not as bad as it could be and doesn't detract from the overall look on the shelf. I think that Hasbro could easily release it in the mid-size "starfighter" assortment and still include the original pilot figure, since the ship is quite a bit smaller in profile than any of the other mid-sized vehicles, and since vehicles it was released alongside back in 2003 (such as the Hailfire Droid, Jedi Starfighter, and AAT) have all been rereleased in the mid-sized vehicle line since with the same features and at the same price.
Other small modifications I'd like to see:
-Rebel Alliance Snowspeeder with red markings (heck, put Wedge and Janson figures in it and make it an exclusive, as was debated last fall, and I'd be all over it)
-TX-130 Interceptor Tank (Imperial Colors, or lack thereof). I'm surprised we didn't get this before the blue 501st-themed deco, since the Imperial version was in both Battlefront games (IIRC; it's been a while since I've played the first one).
-Vulture Droid (TPM redeco). I'd be highly surprised if Hasbro didn't release this next year with the 3D release of TPM. It's a great toy, and it would enable me to finally get rid of the 1999 three pack version.
-Anakin AND Zam's Airspeeders from AOTC. I don't know if these could even be done well using the 2002 molds, as my main problems with both are the inability to seat figures comfortably (I have Anakin and Obi-Wan in mine, and they both have their door-side arms hanging out) or at all (Hasbro's claims back then that "Zam does fit, you just have to fiddle with her a little" still makes me retch).
Also, to blatantly steal from Jesse's list further, a blue McQuarrie A-Wing goes without saying.
