I think the fact that these two are still so close this late in their lifecycle, just illustrates how great this generation was and still is. As far I remember, something like this never happened in game history. And the people that really benefit from this competition are we, the gamers. Sometimes I really wish to be younger and have more time to play all the great games that came out recently.
In my opinion there is no looser in this generation, no matter who ends up in which place. There is Nintendo, selling more home consoles than ever before, Microsoft was able to really strengthen and extend their position in the console industry,and Sony getting rewarded for their long-term thinking.
I really hope the next generation will be as much competition as its predecessor (I still believe in WiiU to be part of it). Actually I still have no idea which horse I will be riding next gen, as I try to be more patient than last time.
enjoy the games fellas!
