PlayStation 4 design 'almost' final

The PlayStation 4 design Sony unveiled this evening is not final, but it's close, according to Sony Worldwide Studios president Shuhei Yoshida.

"It's almost final," Yoshida said, noting that there are "some subtle things" that could change before the next-generation system launches later this year.

In addition, Sony confirmed that the plastic piece that holds the system upright when positioned vertically will be sold as a separate peripheral. Pricing was not divulged.
