I think that in the end, this is going to be a win for most gamers.
This was such a PR shitstain that I don't think anyone is going to think it's even worth it to mislead consumers anymore for short term gain. It was definitely misleading, on purpose, to create the impression that it was a permanent exclusive. I think that the press, and gamers, will now hold their feet to the fire if this happens again with a large game announcement.
And then of course, the game will eventually be playable by others since it's only timed exclusive, so that's a plus.
The only question now is if it's going to PC in 2016, or PC and PS4. I don't think the game will ever release on PS3.
