Hopefully Star Ocean can join that list as well! Anyway they must be developing a sequel to one of the generations most successful JRPGs am I right?!
We haven't heard anything from MW in quite a while and they released no game for the 360 in 2008 (remember LO was 2007 japan, BD 2006 japan). Also we know the LO team (MW designs and farms out development) is busy with something else.
I'd assume the worst and expect nothing else from MW on the 360. Remember they cancelled Cry-On, the third of the original three games that Sakaguchi signed on.
