tx12001: Make sure you get some updated information. You only have to register the SYSTEM one time by connecting online, after that you can remain offline indefinitely (so long as the game itself doesn't require internet, like TESO will). It is true, though, that no disc-based 360 games will work on it (unless you hook the 360 up to it and use the 'play-through ability') but they are exploring the option for the 'cloud'.
To answer the original question; I certainly am! I have several friends who will also be joining in, so almost a full group!!! Only catch? Ebonheart Pact!
