Current lenses, on cheap projectors, can show the interpixel gap clearly, quite often, with 1080p projectors. Actually getting the detail of 4K won't require a whole new design in this regard. For that matter, Panasonic didn't come out with any new lenses with the introduction of 3-chip 4K projectors. They use the same lenses which were used with the 3-chip 1080p projectors.

It has been determined that the TI chip can't resolve individual on/off pixel lines because they are overlapping pixels and the shift they are doing doesn't actually pass the on/off line test. It shows up grey instead of black/white.
1080i was certainly HD, as was 720p. In fact, by the original definition of 'high definition', which predates current marketing by decades, high definition is the resolution to distance ratio wherein adding one more line of resolution doesn't improve image quality at all. So, a 19" TV from 20 feet away was considered 'HD' way, way, way back when. But, most didn't know that. 720p and 1080i were marketed as HD (marketing definition) and 1080p was marketed as 'Full HD'. So, while both 720p and 1080i were 'HD', they didn't fit the marketing term 'Full HD'. These two arguments aren't really the same though because a 4K chip needs to pass individual on/off line tests cleanly to be 4K. A grey muddling isn't the same.
When I spoke with TI a couple of years ago, they gave no indication that they were interested in, or working on, a 4K consumer chip. Yet, even from the commercial side, the push for 4K is tremendous. People want 4K in offices, and they want it at home, and much like 1080p was a buzzword long before there was any 1080p content, we now have the same with 4K and a industry that isn't prepared for it. I don't fault the engineers for getting this product to market, based upon their Pico technology, but we will have to see how these deliver. It also needs to be questioned why they haven't even offered a single chip full array 4K chip when they do have them already in their 3-chip models. I actually have no idea why this is as it should have allowed for some models in the $10,000 - $20,000 range at the very least.
Yes, I know it's difficult, and I'm not faulting any single company really. But, the Sony HW45ES may still be the best looking model out there in terms of overall image quality for quite a while based upon budget and currently available content.
