They doing it so they can keep the IP like fox does with Fantastic 4(Hey, we made a #$%#$^ 3rd movie so you can't take the IP from us!). I'm angered, to be honest, and very frustrated with them. Unless proven otherwise(Such as deal making it and they get to keep Statesman or something) they betrayed us as far as I am concerned.
Here's to looking forward to the spiritual successors at least, so far they seem to be far farther along than the talks at this point. Heck, Ship of heroes may be the game at this rate.
