That's what I would do if I were them. They could make a real breakthrough in gameplay experience if they wait for the next generation consoles. They could even be one of the front-runners, leading the next gen industry with a revolutionary game like SC:Ghost, making the SC universe a seeming reality. If they released it for the current systems, how good could it be? It isn't going to beat out games like TR:AoD and LoK

R2 as far as that genre goes. They may as well wait, they'd accomplish a lot more.
