From Rare: "Co-op over Live is currently in the last stages of debugging and should be available very soon. And there are firm plans to release more downloadable content soon after - details of which will be made available soon."
It has been known since before the release of Kameo that they intended all along to have co-op play over Live but simply ran out of time. It's nice to see them follow through on this and I can't wait to see what other goodies they will have as well.
