Gearbox Only Responsible for Aliens: Colonial Marines’ Multiplayer?

Rumors have surfaced which claims that Gearbox is only responsible for Aliens: Colonial Marines’  multiplayer, and not the rest of the development.

A forum post from a Gearbox staffer reads:

Hate to say it, but I wouldn’t get your hopes up too high for Colonial Marines. I used to work at Gearbox, and the development of that game has been a total train wreck, going on what, 6 years now? Gearbox isn’t even making the game, except for the multiplayer. Primary development was outsourced to TimeGate Studios, which has a less than stellar past.

I hope it proves me wrong, as I still have alot of friends still working at Gearbox, but I am expecting it to be average at best.
