A popular insider is arguing that Sony won't allow PC ports on future Xbox consoles. Many gamers disagree since any Windows-based system should support Steam. Microsoft may soon release an Xbox handheld that could act as a test case for booting PlayStation's cross-platform games.
We seriously need to ditch console exclusivity. No consoles today (other than the ones Valve has made/are working on) are even remotely worth having exclusives for. Just let people play games on whatever platform they prefer.
