Example time
Say ten years from now Bungie said they would release the original Halo with better GFX/sounds/etc on the PS4 and Xbox 900 at the same time for $15-20, yet the Xbox got the release first, then (for instance) 6 months down the line the PS4 got the release and Sony avoided responsibility by saying 'oh we were optimizing it/waiting for a publisher's ok/developer's green light', meantime people moved on to newer games, and Bungie were left looking stupid
Slightly OT: I would LOVE a Deception remake on PS3 though.....
