"Slightly superior to the PS360" sounds pretty darn good to me to be honest, I understand all the mainstream gamers are all about the graphics, more power and everything, but if its graphics you want then PC its really the way to go.
Now going back to consoles,I support Nintendo's concept because I dont want the next generation to be decided over the "slight" difference on graphics, will Nintendo revolutionize the industry once again? they might not, but at least they are exploring alternatives, Motion gaming might not have been what everyone wanted, but it was a success at least financially and I dont care how much you hate motion gaming and Nintendo but every gamer must accept that games such as Skyward sword, Metroid Prime 3(to name a few) played perfectly.
Besides how important are graphics now-a-days when games like mine craft and Temple run are being downloaded more time than any console franchise can even dream, true they are cheap or free but I really do know people that rather play these games than console games without the price of the mentioned games being a factor.
