Video game industry insiders are predicting that the PS4 will gain a 66 to 70% market share this generation.
For the PS4 to gain two thirds of the growing video game market share will be an impressive feat. This will depend on how well it will fare against the Xbox One of course. Nintendo led the previous generation with the Wii, but is struggling right now with the Wii U.
2014 will be a better indication to see which console comes out on top early.
