I was reading this about the xbox 360. One thing I was thinking about is if you could have regional servers, it could speed things up. However, most games don't need a server running all the time. If a server went down, for let's say maintence, then the customer's could use the next one.

Another thing is if one of the big costs of a mmorpg, is having the servers architecture. If microsoft could take care of that would make it a whole lot easier to develop games. For example, if they built that into the xns club, it would make it a whole lot easier.
