Any reason to even buy a new PJ at this juncture??

From what I can tell from the latest current new crop of popular a JVC, Epson, Panasonic and Sony video projectors, I can't help but to ask myself, "why even consider buying new right now?!, if my picture won't get any bigger or better???"
Face it, most anything new -and affordable, if practical or even logical? - in a home theater dedicated video projector, is still 1080p! Yes, we're still pushing 1080p video projectors to the consumer masses, it appears, merely for the sake of coming out with a new product every year!! I'm not being fooled into thinking anything else, I assure you.
Why would I plunk down a couple/few thousand on a new 1080p video projector, which has the same main basic features which were available on the last couple years generations products?! Answer: I wouldn't!! Nothing new under the sun here, IMO. Im sticking with old standbyes for the time being.
And well then what's happening with promised TRUE 4K projectors? Well here's what projectorcentral reviewer had to say about he $15,000 sony 4K 600ES projector that's under review:

"We've been working with the Sony VW600ES since its arrival in late November. We love this 4K projector for a lot of reasons, but we've been unable to complete the review due to a lack of native 4K source material. Sony says it is on its way, but it has not yet arrived. We cannot finish the review without testing it with native source material, so it is in a holding pattern at the moment..."

I THINK THAT ABOUT SUMMS IT UP FOR 4K PROJECTORS AND LACK OF AVAILABLE CONTENT!! ..basically, there isn't any, so why bother right now spending big for 4k projection?! VERY few of us are likey going to, Im certain.
This weeks CES show has unveiled some large panel 4-6K native cuved flat panel displays, that will likely all but eventually doom the video home theater video projector, as these panels get cheaper and bigger! IT appears to be headed this way. Right now, the video projector can get the job done for cheaper, in the right setup.
So what I can see, is hang on to your old 1080p, and we're going to be waiting, or maybe not at all, for 4k projectors and source to be a viable option.
What you think?
