I give it a 9/10. They came out with great games from the get go. It slowed down in a few parts but FFXV, KHIII, $399 price point and the nut-shots they took at MS for used games and DRM were priceless.
I am disappointed that they will require PS+ for multiplayer games. I did not see it coming but for a cheaper price on the console, I'll have to deal with it. It will take 2 full years of subscription to make up that $100 dollars savings but with all the content PS+ on PS3, i can't see myself bitching about it too much. You can't have it all.
Overall, fantastic conference for both MS and Sony, the strongest in recent years.
