Article is utter testicles from start to finish.
They would not release the slim so quickly and without any publication, a couple of months maybe, but next month? No chance.
They certainly would not release their next gen console early next year, they will announce it at least a year in advance imo. Late 2010 is a distant possibility, but early 2010? Again no chance.
Not so sure about that August possibly to early, but September after TGS would be about right. Not going to see anything official until the slim is about ready to launch, it would put of people buying the old units unless they was priced to clear. The sony wand is due next spring but like you said a new console i doubt it, not going to see that till 2012 i reckon.
