Update (10/25/13): It seems the drama continues for the Xbox camp regarding this controversy as Albert Penello, the lead planner for the Xbox One, has been turned down by "a guy that runs 3rd party relations for Xbox". An active member on the same forum said rumor originated, Albert has went on record claiming to have asked about the resolution in Call of Duty: Ghosts on the Xbox One. The response he was given was rather daft: "You don't need to know."
Now that seems to be a blatant attempt to simply avoid the question, but Albert did go on to explain how "this is an Activision product" and that "no one at Microsoft knows." That may be true, but given the legs this rumor has obtained, you would think fans would have gotten an answer by now.
More on this story as it develops.
As we get closer to the launch of both the Xbox One and PlayStation 4, more information seems to be coming out regarding multi-platform title's and the performance difference between the respected platforms. With several reports indicating that Sony's console has the edge in performance, it seems to be a weekly occurrence of "what game is next" in the line-up of superior ports.
In the past month, the list has included titles such as Watch_Dogs and Battlefield 4. With the notion of being "graphically superior" on the PlayStation 4, you could imagine the eruption when rumors started circulating that Call of Duty: Ghosts would be running at 720p (native) on the Xbox One in comparison to the PlayStation 4's 1080p (both versions at 60 frames per second).
This rumor comes from the incredibly popular and active gaming forum known as "NeoGaf." Now, getting this out of the way early, these are just rumors, with little weight behind them. The only merit to the rumor is when a member of the forum know as "CBOAT" came in to elaborate, claiming that TitanFall was also running at 720p.
Whats the weight in CBOATS word? He is more often right than wrong regarding Microsoft news (Sony news not withstanding), so when he(or she?) speaks, it's taken with some worth. It also is important to note that IGN chose to show off 1080p PlaySation 4 footage of Call of Duty: Ghosts, footage that has been historically confined to Microsoft platforms.
Now, that's rumor, a rumor that has very little weight behind it in all reality. What isn't rumor, however, is that the PlayStation 4 variant has been confirmed to run at a native 1080p by Sony's very own Adam Boyes. This announcement was in direct response to the recent rumors, leaving the ball in Microsoft's court while fans await a response.
This story is not dead, but it has gain a huge amount of traction over the last week, so be sure to check back as updates come in, one hopefully being Microsoft's response.
