Sounds interesting, especially the 90 CRI part. I'm a tad less impressed with the $152 / 600 lumens part ... Although they mention that they use 20% less power, there seems to be a reluctance to publish actual power / lumen values for these LED setups (or have I just missed them??).
I don't know about your 5 year timeline - at least for residential lighting (vs plant lighting). The advances / improvements seem to be coming at a pretty good rate. If the industry believes that energy efficiency is here to stay and the bottom won't fall out again like the 70's & 80's, they'll start to put some serious effort into research ...
