I agree with those that have said we'll see more of a focus on Clone Wars stuff (along with the big GI Joe and TF push with both movies coming this year). That being said, I hope we get a look at some more of the Legacy waves. I'm guessing we'll see the ESB wave that's supposed to be up next after the ANH wave, but there's a good chance we'll see that prior to Toy Fair. It seems to work out that way usually anyways. I'm hoping we get a look at the rest of the "spring waves", which in total covers the ANH, ESB, AOTC, and ROTJ waves. According to Hasbro's breakdown, those are the four "spring waves", and then we can see the "Fall waves" at Comic Con.
I know I'm probably in a bit of a minority here, since many want all-new vehicles, but I wouldn't mind some news on some more re-done Original Trilogy vehicles. They don't necessarily have to be BMF sized, like an AT-AT, but even an all-new version of the Snowspeeder or AT-ST (although I'd like to see larger vehicles like the AT-AT, Slave 1, etc. eventually as well). I'd also like to see Hasbro go all out with the new Jabba the Hutt, with a nice dais and backdrop like mentioned earlier.
