This is more than early adopters coming to the PS4. There are well over 100 million potential customers who will be replacing PS3 and Xbox 360's with PS4's over the next few years.
No, that's precisely what early adopters are; like I said, things have just become more and more front-loaded in gaming, especially as of late. Furthermore, there's no sign of more people wanting to replace their systems just because the PS4 is out .If anyone has an uphill battle it's Sony and MS because there really isn't any difference between the PS4, XB1 and their predecessors besides slightly pretty graphical effects. The 360 was slow as hell to sell until 2007. The PS3 took THREE YEARS to hit its stride. And this is only going to become the norm from now on. Gaming is a luxury and people can deal with not upgrading their systems, especially when the cheapest of the HD twins comes in at $400 without a game, online subscription, or more than one controller. I don't ANY of the new systems doing well their first year, and that's going to be a wakeup call for all parties involved.
