Based on COD: Ghosts and BF4, resolution wouldn't matter to me. Because unless you're gaming on a gigantic screen, the difference is negligible. However, what I am concerned over is that this could be a litmus test for the XBone's performance down the road. If the PS4 continually outperforms the XBone, gamewise, that will raise issues for the gaming community. Because the performance gaps could become greater. When the PS3 was "hard to develop for", with each subsequent multiplatform release, the performance of the PS3 versions of games got better and better until they hit parity or above the 360 version.
Now we have a situation of a console that's "easier to develop for" that has objectively "more powerful" hardware (as opposed to the PS3 being more powerful than the 360 but harder to develop for) than the competition and we have two examples of the PS4 version of a game significantly outperforming the XBone version (although looking at a TV screen within 6-9 ft won't give you much of a difference visually from your own perspective, the fact remains that under the hood, running 1080p natively is more intense on a system than 720p natively).
So sure, right now, resolution isn't the end all, be all. But it has implications considering what we know about the PS4 and XBone's architecture.
