"What I would say is it's unlikely that we'd launch anything within six months [after Aliens vs. Predator], but probably nine months, eight to 12 months possibly," said Sega president Mike Hayes to G4TV. "Though we literally are looking at that at the moment and a lot of is going to depend, as well, on how successful AvP is at the box [retail]." Aliens vs. Predator is scheduled for a first quarter 2010 release, meaning that Colonial Marines might be pushed into 2011 if demand for Rebellion's game is less than expected.

"It's what level of 'well' does it do," added Hayes, "do we then determine when we want to bring the next one out and then, of course, determine what the third one in the series is likely to be."
