I am just thinking about this and I feel we probably will using pixel shifting in the future. As resolution increases, the LCD/DLP/Lcos panel will get bigger. I feel there may be a limit to how big these panels can get before they become too difficult and expensive to produce. So, pixel shifting will be necessary in the future.
Although pixel shifting is very new to projectors, the principle is very old. Our old CRT TV/monitors have been doing the same thing for decades. The 3 electron guns in colour CRT can only light up 1 pixel at any time. But it sweeps across the screen at an extremely high rate. So what we see is a full screen image instead. WE cant see individual pixels being lighted up 1 at a time. Sometimes we can notice screen flickering if refresh rate is low (~60Hz), but at 85-100HZ and above, we cant see.
Although close up photos have shown a distinct difference between native 4K and pixel shifting, but I don't think anyone will be sitting that close to the screen when watching movies. At normal view distance of ~3m, it is extremely hard for human eye to tell the difference. There is still alot of room for improvement for pixel shifting. It can only get better and I believe its just a matter of time before we can't see the difference at all.
