PS4 to lead all consoles with 51 million sold by 2016 - IDC

[Skidonti]

I think it has a fair shot at 50 by the end of 2016. But even in the best case I don't think it'd be much higher.
I'm still thinking we'll see hardware market shrinkage over last gen overall, especially with pricier consoles, so that'd be part of it.
