I agree about the challenge these DLPs will have to wow us uber-geeks and offer a compelling case for an upgrade.
Pixelworks FI being "great" or offering true 120hz at 1080p or above would likely convince me to pull the trigger.
Smurfs 2 being ripped is changing my cost / benefits analysis for spending 3 grand for 4K, absent the above two reasons for upgrade.
I think it's possible to modify the de-gamma LUT on my current DLP, and if not, use a 2.8 gamma value to decode PQ and then output that in 10-bit and get a faux-HDR image in glorious high bitrate, downscaled 4K, 444, P3 content. I may be able to live with that for another year.
