Let's see how the foldable screen thing shapes up in the next decade or so, because it's not going to become a realistic option anytime soon, that's for sure. And above a certain size there will almost certainly always be a market for projection anyway.
I mean, the OLED technology has longevity issues, issues related to burn-in, color drift and what not. It is also very expensive, and a 120 inch "foldable" OLED will in all likelyhood be enormously expensive even 10 years from now, if it exists at all by then. And this isn't considering whether or not they have sorted out what seems to be the inherent weakness of longevity with the OLED technology. If people are going to splash thousands of dollars on such a screen, it has to last longer and be more stable than the current ones.
In other words, I think there will always be a niche market for projection. And even if the price of OLED, or some other screen technology where the picture emanates from the surface itself, ever comes down in price and ease of use to compete at those screen sizes, I still think projection will own a part of the market simply because of people who prefer the look of a projected image. Much like vinyl LPs in music, or mechanical watches, there is something beautifully "analog" about a projected image where the light reflects off a surface. It has a special character to it that's hard to put into words, but it's definitely different than the pixel-lit lightpath that TV panels give you.
