Square Enix Europe announced this morning that it has entered into a "strategic partnership" with Gas Powered Games to release Supreme Commander 2. Squeenix states that its affiliation with the House of Chris Taylor is part of the publisher's "goal of increasing western development efforts aimed for the global markets."
The original Supreme Commander was published by THQ, so we're a little confused as to how Square Enix got a hold of the license, unless GPG owned the rights all along. We've contacted THQ, GPG and Squeenix for clarification. No word on when Supreme Commander 2 will mech march to retail.
Update: Doing a bit more research, it appears GPG owns the rights to the Supreme Commander franchise.
