I believe the XCOM franchise is owned by Take2 with a XCOM 1st person shooter being developed (Ken Levine) and a strategy XCOM being developed by Firaxis (Sid Meiers). That is, if you believe rumors. I know someone that I work with who has been to Firaxis' facility and "saw" a "new" XCOM poster and he is a pretty reliable sort. That, of course doesn't mean that it is not some sort of marketing for the XCOM bundle.
