BioShock Infinite Combat Design Director & A.I. Lead Leave for Microsoft, is Irrational in Trouble?

Could BioShock Inifinite studio Irrational Games be in trouble? Just a month ago, the studio saw its Art Director, Design Manager, Senior System Designer, Director of Product Development and one of its writers leave the studio (via Joystiq). Now, more key personnel have left the studio once again. This time, it's BioShock Infinite's Combat Design Director Clint Bundrick, and A.I. Lead Don Norbury.

Both Bundrick and Norbury's LinkedIn profiles state that they're now working for Microsoft, though it's not known on which internal studio or game they're working on. 

Couple these departures with the ones a month ago and factor in the game's absence in the public eye…well, you can understand why some people are concerned if something's amiss at Irrational.

Hopefully, the game's upcoming new trailer will alleviate fears, no? Do you there's something foul going on in Irrational now or are people just making too much of it?

BioShock Infinite is scheduled to ship in February of 2013.
