When will the PS4 reach 50% total market share?

[JoeTheBro]

Just for 2014 it's at 60%. Keeping that ratio for the rest of forever, it'll reach 50% marketshare upon reaching 16.8 million sales.

Q4 2014 seems like a very solid answer if Mario Kart and Smash have a minimal effect. I hope they don't though, so I'll go with Q1 2015.
