I'll be going with the Next Sony Console.
My reason for saying so is that
Nintendo has been since the gamecube era , making the exact same games over and over. Animal Crossing was fun , then when i saw it on each system after the gamecube with pretty much zero difference meh , same with Mario , Link , Samus , etc. I would enjoy seeing Nintendo start just making the games and remove themselves from the console wars, i believe they would do better. I like the games sometimes.
The Xbox has a completely different reason for myself, having had a blast with friends playing halo , i purchased an xbox360 back when it first came out, enjoyed it , found the games to be very good. However after my system red ringed for the first time , it all went down hill. I had the second one which was from microsoft not work at all out of the box , the third one come with a free copy of crackdown with a sticker on the back of it which made it unplayble , that system lasted for about a month before it died. My fourth replacement sratched the discs, the fifth red ringed after 3 months of play. My final unit has a broken cd tray , sounds like a jet engine when i turn it on, i haven't turned it on in over a year now. Plus the added effect that most games that were XBOX ONLY , now are getting the Sony treatment , why buy an xbox when the games come out for the PS3 eventually, and yet the PS3 ONLY games do not come out for xbox.
So Sony wins this one for me.
