This is either a hoax, misinterpretation of information, some half-truth, or entirely true. If this is entirely true, then there will be plenty of time to talk about it when it offically is revealed. That's why I'm not going spend my time pondering whether some rumors are true or not. Giving credibility to rumors gives hoax-makers and jump-the-gun/non-fact-checking pundits reasons to keep putting out these statements. They can say, "Even if we're right only some of the time, the public eats it up so we'll keep doing it."
Again, if Sony is going to, er, refactor their graphic chips 2 months before launch without telling any of their developers and without testing rigorously against all the software, there will be plenty of time to talk about the pros and cons of this if an announcement is made. But giving credence to rumors just feuls the fire for sites like www.theinquirer.net. Here's their latest gem.
