Home Theater Redray Laser Projector is going to appear within 2012.Doesn ´t need calibration and the laser is nearly lifetime (25000 hours) .It will cost like JVC DLA-x70 and its LCOS chips are 4K.I am going to wait to buy one.
You might want to wait and see if it's any good yet - a couple of years ago people were saying that LED PJ's would be the next best things, but not much has happened.
