I am stoked and bummed at the same time.
I really want to play it, it would be perfect for my little Star Wars MAME cabinet (if in fact it is in mame). Seems like fun.
But on the other hand, it seems somewhat boring. Part of the appeal of the other two Star Wars vector games is that they jump from different 'zones' or stages rather quickly. This ROTJ seems to be free moving around shooting whatever tie fighters you want. If that is the case, wouldn't it just be better to play the PC xwing? (as Scumbum has pointed out the similarity)
