Sony has a couple of sweet, sweet numbers to report with regard to sales of its gaming hardware. The PlayStation 3, that venerable old powerhouse of console gaming, has surpassed 50 million units shipped around the globe, while the PS Move controller introduced late last year has also kept pace and rounded its own milestone with eight million units shipped. We say "shipped" in spite of Sony calling these sales, because what Sony reports are sales to retailers, not end users (the company calls 'em "sell-in numbers"), so they're not directly comparable with retail sales of the competition. Still, numbers are numbers, and these are pretty big ones. Full PR after the break.
