XCOM fans can perhaps rest a bit easier now, knowing the new "reimagining" will not be developed by the BioShock 2 team per se as claimed by the publisher. Truth of the matter is technically 2K Australia will be developing, though recently they've switched to the 2K Marin name. It's said this team contributed significantly to BioShock 2, but the core creative team was located in Marin, not Australia.
BioShock 2 is a well-enough designed game, mind you, it's simply not the game most fans would want a team to jump from.
2K Games declined to comment on the name change, but said they'll be "talking about XCOM, the team and everything else in the near future."
