People don't seem to realize something...
Why would you be laughing at MS? There's zero confusion for Xbox one owners here. We know we will be playing tomb raider holiday 2015. The only people the vague statements could possibly upset would be Ps4 owners, maybe PC owners. Phil Spencer doesn't care if people that don't own xboxes are salty.This isn't a problem for Microsoft to deal with, it's really an issue with CD and SE.
The more Phil Spencer upsets Ps4 owners the better a job he is doing. That's just the nature of the competition unfortunately. If you are completely anti Xbox but get upset when an exclusive game or content isn't available to you, then I think this is going to be a veeery long generation for you indeed.
