I like Scott's lineup as well, and hopefully we will see something spiffy for each 3D release. Like it has been mentioned, they still have to be careful/cautious about it though - as I'm sure they don't want a big item hitting clearance instantly each year either. Plus, how long are the 3D re-releases actually going to stay in theaters? I remember when the OT SEs came out, and I did go to each of them, but I'm pretty sure the box office numbers fell with each release (with ANH doing by far the most business), and none of them staying in theaters for a particularly long time. Since they are aiming for another February release, and with all the 3D movies these days, I'm guessing they'll be making way for the summer movies pretty quickly. Not that I don't want them hanging around for awhile, I hope they do, but it isn't quite the same "movie year" scenario as it was for something like ROTS, where it was basically "the movie" for the entire year of 2005 (and beyond, as toys go).
Of the list, I'm most excited for some sort of Death Star as well. Although I think many collectors would like to see the hyper-detailed, modular sort of set that CHEWIE mentions, I think a "play" set is more likely as well. I wouldn't have any problem with them updating and/or following the vintage model for that either. That was really sort of the holy grail of the vintage line, and something I always wished I would have had as a kid (or even now). The chance to get an updated version would be pretty sweet. If Hasbro could strike the same balance they have with the Falcon, AT-AT, AT-TE, etc. I think it could be a nice looking piece, as well as a "fun" toy as well.
As for some of the other ideas, honestly, I wouldn't mind seeing the Royal Starship or Turbo Tank again, simply because I had to pass on them the first time around due to budget. But, at the same time, I could see them being pretty risky (the starship in particular) as far as the big items go. The Turbo Tank did hit clearance pretty quickly here as well, and sat more than the other big vehicles have - and we've never seen it again. The AT-TE and Falcon have both gotten re-releases at TRU over the years, and I wouldn't be surprised to see either (or the AT-AT) again. Its tough to judge with the big vehicles, as it seems someone always finds them on clearance - and sometimes at crazy clearance prices, while others seem them disappear quickly. I'd say, at least locally, the AT-AT has by far been the most successful. The AT-TE did pretty well too, and the Falcon wasn't bad - although I think the starting $150 price held that one back a bit. I have a feeling sales would have been a lot brisker if it was priced at $100 like the others have been.
