I mean is there any way for Sony to screw this up?
They have the best chipset of the three and the most reasonably priced one since both Nintendo and MS got hung up on including expensive control devices in their boxes.
They are a full $100 cheaper than MS. Their system is easy to develop for. Third parties reportedly love it, so it will get a ton of devleoper support and perhaps have the best multi-plats.
Sony's embraced indie gaming as well and is even scooping up some of the more promising ones as exclusive. Their 1st/2nd party studios have gotten stronger over the years.
Nintendo doesn't have a Wiimote type craze to disrupt this console cycle either, and Sony isn't anchored to a $599.99 price point this time around either. Stripped of casuals, it looks like Nintendo is headed back to GameCube (worst case) or N64 (better case) levels. Which leaves MS.
Their launch lineup is a tad weak I think, but will be offset quickly by having so much developer support. Is there any way the PS4 doesn't win this gen worldwide? I mean sure, MS will probably give them all they can handle in the US, but globally ... looks like they have this gen on cruise control.
