I'm with you there on the space for all this big stuff Jesse. I think the big vehicles are great, but it really is becoming a challenge to get everything out and displayed. That's the reason why I'm always toying with either getting rid of the PT/CW era stuff, or just packing some of it up. Then I look at the AT-TE, or even things like the ARC 170 or Gunship, and I just can't put them away. Plus, a lot of the starfighter and deluxe line vehicles from that era are pretty spiffy.
As far as the Imperial Shuttle, I don't see a reason to redo that ship either. I actually kind of like the previous version (I have the Target exclusive one from a few years ago), and don't have a need for a larger or changed one. I'd still like to see more OT re-dos, and I think the starfighters Jesse mentioned would be great candidates. I'm also in for a Slave I if that happens, although I hope we get an ESB repaint of it if we're getting the CW version first (which sounds likely). Otherwise, they are starting to cover a lot of the rest pretty well. We got the Falcon, a new AT-ST, a new AT-AT/Snowspeeder/Cloud Car on the way, the big winged TIE, and a pretty nice Landspeeder from the SAGA line. I do hope we see some of the rest get redone too, as well as more of the beasts (particularly the Taun Taun)....but I'm not sure if there is much left that would qualify as "$100 big" projects, aside from something like the Sail Barge or Death Star.
