2K has apparently said that BioShock 2 is not going to be an Xbox 360 exclusive.
It will be coming to the PS3 too, so stay calm.
CVG has received confirmation from 2K that it will not be exclusive to any one console. No word about about it being a timed exclusive though.
Rumors were popping up all over the place that Microsoft was pushing a timed exclusive, a result of 2K listing the console schedule as TBA.
Hopefully, if it does come out on Xbox first, PS3 users won't have to wait another year to get their hands on it like last time.
