This is even a discussion? Playstation 4 no competition. I've always strongly disliked Xbox. While I've never really felt there was a computer system or software where I was the target market, I've always felt that Playstation was the game system for me. So Microsoft aside, I just prefer Sony. Our privacy doesn't really exist anymore, if you want to keep something secret keep it in your head.
Sony is going into this next generation of consoles smarter and hitting harder, already their launch titles and the line up of games looks better than Wii U and Xbox. I'm sure no one was thinking Sega was going to fail before Dreamcast launched, but I wouldn't be surprised if this was the beginning of the end of Microsoft's video
