Does this rumor even need to be really confirmed....? The event has already been announced and it is called "The spotlight turns to notebooks" and Apple releases new notebooks (or at least new updated models) every year. Isn't it already kind of obvious that Apple is releasing new MB & MBPs since they are their only notebooks? It would be much of a "spotlight" on them if they didn't do anything with them. Do people really think that it might not ever happen? That you need a rumor or a confirmation of a rumor? This would of been a bigger rumor if it was found before the announcement. In any case, it happens every year. It is surprising that people talk like it might not happen. It is all just a matter of time.
Plus on top of all that , and forgetting it being obvious already, "confirms" is a pretty strong word, and I wouldn't really say that unless it is an official announcement. Apple has made typos before in the past. If I was Steve Jobs, and I didn't like things being leaked, I'd sometimes put out wrong information by "mistake" or just leak things on rumor sites for fun. Ha ha, lol. I'd have so much fun with that! It would make a good hobby for me.
