With the success story of the fastest selling console continuing today with PS4 becoming the 8th gen leader 3 months after launch, when will the milestone of 80% marketshare come to fruition? If at all. It almost looks a foregone conclusion at this stage in the game.
I believe by January 2020, PS4 should comfortably take at least 80% marketshare. This was such a focal point of the PS2 era that ALMOST came to pass but never happened.
