It's pretty shambolic if IW can't make an average looking game like Ghosts run at 1080p on the Xbox when Crytek is getting arguably the best looking game of the next gen running at 900p. Thats the only reason I struggle to believe these rumours at the moment, unless IW are a bunch of imbeciles it just doesn't make sense. Only other possibility is that first party teams have some more advanced/beta drivers available to them which the third parties don't.
In the short term, I'm not bothered by this news, I have no interest in Ghosts, or the third party at launch (although I am getting FIFA 14 and probably BF4). If this is an issue which won't improve over the next few months, then it's a huge issue for me, but lets wait for some confirmation before doom and gloom.
On a little side note, for all those saying that the ESRAM is hard to program for and is causing the Xbox One issues, don't you realise that developers have been developing for this architecture on the Xbox 360 for the last decade? That's not going to be the issue here, immature drivers/unoptimised OS maybe, and if that's it, then it's reasonable to assume that things will get better over the next few months as Microsoft sorts their act out.
