You can see there's a pretty huge difference between the 800p one and the 1440p one (~4x more pixels), which will probably be what the consumer version will have. With 1440p you will still notice the screen door, especially in the distance (the sky), and it looks like we'll only solve this with the 4k resolution, when the resolution seems to become "normal", and without easily noticeable pixel lines, but it will probably be at 8k when we'll have "retina"-like quality.
All of that being said, I think 95+ percent of consumers buying the 1440p version won't even notice the small pixel lines in the distance, because they'll be so "present" in those VR worlds. Most "normal" people trying it out quickly forget about the screen door even with the 800p developer kit, because they've never experienced something in VR before, and to them it feels very real already. Personally, I do hope they can use the 4k resolution in the second consumer version as soon as possible, but I think the 1440p one will do just fine with all the early adopters.
