That's some pretty silly logic.
The PS3 and Xbox 360 were engineering marvels of their time, ahead of PCs even for a few months; the Wii was a marvel as well for other lesser reasons. Factoring in how much people are willing to play their ps3/360 instead of getting a next gen consoles compared to how quickly people bought the 360/ps3 when they first came out, it's pretty obvious none of these console will reach 100 million..
What's changed from the last generation console launch: Steam, Steam-boxes, buildable PCs that cost as much as these "next gen" gaming consoles, the WiiU, continued support for the previous generations secondary functions that didn't exist even when the 360/ps3 were initially released..
Also, people bought a ps3 because it was only $150 more than a bluray player at the time... think about that.
Thinking to the future, Virtual Reality.. We need 4k resolution at least to make a decent looking oculus game, please tell me right now you think the ps4 can push 8 million pixels... I'd love to hear someone say that.
