If they learned something from SEGA, then they wont.
If they announce the console in one month and have games ready to ship by June, i can see them profiting from the E3 show and releasing it. It would be a master move to 1-up the competition that Microsoft is always ruthless on. Actually, i believe this rumor. Its generally terrible news to Nintendo and Sony as the lead Nintendo gets will be small and they will gain a lead on Sony from the off-set once again. Its devious, and it has Microsoft all over it.
Maybe the countdown on Major nelson is for the release of the console...
Personally, i hope it isnt true though. I'd hate to see microsoft gaining an edge over the competition. I'm well pissed off at them after the 360.
