Um, 2K Marin the Bioshock 2 primary developer ISN'T making XCOM. It's the former 2K Australia, now bafflingly renamed as a 2K Marin "Australian sister studio", that IS making XCOM.
2K Marin, the proper 2K Marin, is totally free to make Bioshock 3 and were pretty much created for that purpose. Take 2 have no reason to pull them off, unless Irrational want to do the next one (like Call of Duty going between Infinity Ward and Treyarch).
