I think you're going to be wildly wrong, but kudos for your prediction anyway. I think next generation will play out generally like this generation, without the wildcard value of the Wii - I'm not sure how the Wii-U will perform in all honesty. edit: That means - Microsoft in North America, Sony in Europe and Japan. Not sure where Nintendo will perform best.
Saying things like "One of the main selling points of the PS3 was that it had internet browsing capabilities" and talking about graphical advantage of PS3 over 360 are odd. I don't know anyone who'd consider PS3's internet browser as a selling point, except you. And nobody I know who bought a PS3 did so because they thought it had better graphical capabilities - they bought them because of familiarity with the brand and wanting to play certain games.
