On topic: This is a great leak and very exciting if true. I had suspected some of these things, but was surprised and greatly so for some more of this explanation regarding the 2 devices and the clarification of the "always connected" rumors.
I knew it was most definitely NOT going to be a Durango requirement to play local games.
Granted this is still just another rumor. Can't wait till May! I will be on my honeymoon when the NextBox is revealed! (if may 21)
