I wonder what is even the point or incentive to buy a Next-Gen console from Sony or MS, other than the lack of money/unwillingness to play on a PC?
There was a time when consoles had their firm right for existence, but with PC hardware having advanced so fast and services like Steam making PC gaming a lot cheaper and more convenient, Next Gen home consoles will become more or less obsolete unless you're a big fan of their first-party offering. And with the rumors confirmation of Valve's Steambox, PC gaming will get even a greater push, because developers/publishers won't be able to afford to ignore the Steambox, and porting Steambox games to general-purpose PCs shouldn't be much of trouble.
Yeah, Nintendo is actually quite smart with their decision of doing things their own way, I have to agree. Their hardware is definitely tailored towards exclusives, both First- and Third party. No point in playing a game on the Wii U that is also avalibale on all other platforms.
I foresee Sony and MS furthermore to push "filmic" style games. More hardware power will directly translate into even more cutscene heavy games, while Nintendo's weaker hardware offering will inevitably force developers to concentrate more on gameplay, not on cinematographics.
Therefor, Nintendo will win again. And Valve. And me.
