The one thing I will say in the PS3's defense is that this gen's Wii led forray in to new markets has blown the normal console generation rules apart, specifically in the market leader branch. Though I doubt the PS3 will come close to 100 million, it is feasible for the non market leader to still find a huge market. If it were to make 100 mill, just imagine where the Wii would end up!
The 360 has admittedly slowed down, and the PS3 should see rising success as the price drops. But unlike the PS2 that had absolutely no competition in terms of third party support and the PS1 which could offer entire game genres the N64 couldn't touch, it's hard to ignore that the 360 is still getting most of the same third party games. The OP mentions Final Fantasy as a reason for the PS3's eventual 100 million status, even though it failed to move hardware in the one market that it's exclusive to the console in.
There are a hell of a lot more people buying consoles this time around, but a lot of those people are still going to be getting the other two consoles.

Serves me right for challenging his sales predictions!
Bet with dsisister44: Red Steel 2 will sell 1 million within it's first 365 days of sales.
