Sony stock sees a surge after the Xbox One was unveiled

Just under twelve hours ago now, Microsoft unveiled their next-generation console, the Xbox One. Funnily enough, at the same time, Sony saw their stock prices lift by a decent margin, from $20.94 to $22.55 when Microsoft started the Xbox One event.

Microsoft's stock price didn't shift all that much during or after the event, simply moving from $34.99 to $35.02. It seems as though I wasn't the only one that wasn't blown away by the Microsoft Xbox One, so could this be the start of something interesting for Sony?
