Yes totally irrelevant and no lies whatsoever. we should ignore that the game was propped up as a 1080p game 8 months ago when it clearly can't hit it, at least in the visuals they want to show.
The game is not out. It isn't 1080p or any other resolution. It's an upcoming product, which will be a resolution at launch, but until it launches, they can't have possibly lied about it.
I'm not saying it will be irrelevant. If it launches at sub-1080p, and they did promise it'd be 1080p, fine, let's have a thread about it at that time. This is not Halo 5, it is a beta for a fraction of the multiplayer suite.
