While PS3 owners are already enjoying the demo for Tecmo Koei's Quantum Theory, it looks like the denizens of Xbox Live will have to wait a little longer. Unfortunately, we don't have a solid date for the demo's Xbox debut, with an official announcement saying simply that it will arrive "later this month."

Don't worry about it too much though, we're sure you'll find something to keep you busy for the rest of the month.
