Thanks for your observations on the HD5! Looking forward to hearing more about it.
Does the HD5 use the .67" DMD? (DD's website doesn't have anything posted for the HD5 yet, and the HD4 uses the .67" size DMD.) If so, are you saying the HD5's .67" DMD is performing as well as or better than the Titan's .95" DMD?
Also, you say the HD6, which is an LED projector according to DD's website, is 2000 lumens? Wouldn't that make it the first ever 2000 lumens LED...
