I have Both a Ps3 and a 360. (Like some, if not most user, yes I do own 2 systems...or more). I think its a tidbit ridiculous that, the Bungie.net account doesn't store the characters, but instead the system's account. I believe the sign in process once you hit the A or X button should be/go, Bungie.net> Xbox or Ps3 account> character. This way the Bungie.net account and characters would be interchangeable. I have both friend [s] on the Xbox and Ps3, and I do not like using my alts as a main for playing on one system or another. I know others have to be in or near the same boat.
