I am waiting in hot anticipation for the Assault Gunboat. Realistically it's more likely the TIE Defender will be appearing, wherein I will also buy multiple copies since that's my favorite TIE fighter
TIE Fighter and X-Wing had a lot of thought put into the storyline, balance of fighters, and so on that I also think it deserves mention. I think a number of players- maybe not a great many but a few- immediately think of the computer game when they hear about the "X-wing game" and I also think it should be honored in some way within the miniatures game.
It's remarkable to see Stele and even see him appear so quickly. They almost got it right… according to Wookiepedia Stele preferred to fly a TIE Avenger over a TIE advanced model (Which, technically, you're never able to fly in the TIE Fighter games). I can forgive the little bending of canonicity as long as we'll eventually see the TIE Avenger someday.
