Wonder what this means for a Steam console, particularly if PC games get more love as a result of consoles being x86. I suppose it's good news in the end, with less time wasted on cross-platform shenanigans and more time spent on making games.
I wonder if Sony is basing this decision on negotiations with Valve.
Think about that possibility for a second. What would be the motivating factors? Sony has gotten the shit beat out of them relentlessly in terms of multiplayer/online gaming. PSN has been shuddered for weeks at a time. Partially outsourcing this component to groups like Valve will fix many of their problems, but in return Valve probably would like their whole portfolio of content to be accessible.
If Sony goes x86, it'd be a shame to make such a dramatic shift and not capitalize on a content neutral platform.
