Thanks Jeremy! I'm familiar with your work so it means a lot coming from you!
As for getting the primaries right.... well, only time will tell. Too many of the manufacturers still value specs like high lumen output (by artficially boosting green/blue) more than accurate colours it seems.
A bit of a catch-22: They're only doing what the public asks and the public wants brighter projectors. We need to educate the public as to what boosting green/blue does and how it messes up the primaries. I hope my guide helps push more people to understanding this. Once the public starts to ask more for correct primaries (or at least a way to adjust them), the manufacturers will follow suite. Right now, I'm afraid they're just giving us what we ask for. So everyone please be careful what you ask for!
With so many incorrect primaries, the video processor/scaler manufacturers (such as Lumagen) I imagine are seeing a re-birth in their scaler products as they offer primary adjustments.
