I have been watching all the speculation about Wave 3 ships, and there is a lot of conversation about how limited the options are once we have the B-Wing and TIE-Bomber. There is a lot of conversation about what may or may not be available from the EU. However, it occurs to me that there the folks on here have missed somethig rather obvious.
Disney intends to make a Star Wars movie every year starting in 2015.
So, in 2 years there is a very, very good chance the EU is going to expand, including some new ship designs. Every year after that we have the potential for more new ships, more new pilots, more everything.
Far from the possibility of "running out" of potential ships for this game, we may be looking at the beginning of something truly epic. Especially if the new Star Wars films are as good as the reboot of Star Trek was, and we find ourselves with a whole new generation of Star Wars fans.
My local chapter of the 501st may actually be able to field a full platoon (or company?) of Stormtroopers before the decade is out. :-)
