Mmmm, I actually doubt the B5 evo thing. So far B5 has been their one miniatures game that they -haven't- taken in that direction, and it seems that that was quite deliberately done. It also makes sense that since they have all the AOG Molds, they would quite happily use them to produce the game. GOROPOS was not nearly as widely produced as B5 Wars or FA, so the molds should also not be as worn.
WWE was also supposed to be a sinifigantly different scale then any of their other mini's games, I think it was supposed to be 10-15 MM Scale. I'm sure that they are just putting so much on their plate they want to stabalize things a bit more before they start a whole new project once again.
