There had been a few grumblings going around that Sony's PS3 Slim was about to get some changes to the Hard Drive variants. And while GameStop independently confirmed this for a little while, those ads were quickly pulled. But the rumors didn't stop. And good thing, too -- considering that they turned out to be true. Sony has just announced that there will not only be a 160GB model, but also a 320GB Move bundle coming to market this Fall.
