You really say that comment has any credit.
I'm not saying some other comments don't (like those "no comment", and "currently no plans" and ""currently it is only announced.." comments) have credit or not, just that particular comment above... from where all this started.
I wouldn't put much weight to a magazine editor's comment either, they've known to be wrong on several occasions... for a reason or another.
Ever occured that his (hers?) editorial in the mag stating that fact... no rumour could be a result of false information that he (she?) believes to be true, as many here do too. Magazine editors aren't all knowing, never failing gods you know.
There are signs, yes, but they are mostly imaginary signs pointing to a general direction.
Personally though, I believe it'll come for xbox360 too someday, some form.
