Still, a superior X360 version might play out as a great thing when December rolls around. The RROD issues will probably be forgotten in the most party by the public, and when the 500,000+ people that bought a copy of Madden during last December, a few might get the X360 version.
Either way, even if it doesn't help hardware, it helps licensing revenue for MS, and thats a great thing for them.
Back from the dead, I'm afraid.
