To be honest:
If the PS4 used slow DDR3 ram as video memory, with 30 megabyte of esram, forced a camera. with about 50% less computing power on the video front than it's competitor; forced TV stuff that isn't even compatible in my country, hell, the console wouldn't even be released yet because the Netherlands, besides being among the richest countries in the world, as well as super Microsoft minded, is apparently a tier 2 country, but anyway..
Even if the PS4 was a weak system like that -hell it could even be 100 euro's more expensive than the hypothetical better other system,
Even then, I would still get it.
You know why? Because of Sony Santa Monica, Media Molecule, Quantic Dream, Polyphony, Naughty Dog, Evolution to name some.
I know they would be capable to come up with excellent games.
Maybe Xbox fans feel the same way, but value studios like
Fable,
Bungie 341 studios, Turn 10, ??? well, and all the other 1st party MS studios that created innovative, bafta-winning, genre-defying games.
So yeah, I can totally see a MS- exodus happening
You need power, but above all; you need games.
edit: if a PS4 game is 59.99, and MS could price all the games on their platform at 39.99. I am pretty sure that more people would be able to accept Xbox One as their main platform
