This touches on my one complaint so far. No one has seen Episode VII yet. No one knows if it is any good or not, but already everyone is lapping it up and saying how excited they are to spend money on the new products. Personally, whether I am excited or not by the T-70 and the TIE/FO will be entirely down to whether the film is actually any good or if it's just another Jar Jar Binks atrocity. My sincere hope is that it will be brilliant, but for now I'm not going to get excited, nor am I going to buy any products from the film until I've seen it. The majority of Waves 1-6 are ships and pilots I knew and grew up knowing, so I wanted them as soon as they were announced. Any Episode VII products just don't have that appeal... yet. Similarly, Rebels TV show ships will probably never appeal to me as I think the show is dire.
I guess some people are here purely for the game, with the playing pieces and pilots just being points and abilities. For me though, the whole reason I play this game, is because it's Star Wars and it's the Star Wars I grew up with.
My willingness to buy these products mostly stems from the fact that I like the look of the ships. And its not like there are tons of named characters in the new stuff that I do or don't like. At this point they are selling us the look, not the story. All we have is Poe so far. And aside from the two expansions I doubt we'll see more ships before the film releases. I also don't like Rebels much at all, but TFA will have to be pretty bad to be less acceptable than any of the prequels.
