Thanks for the update, Stinger. I think that JVC was wise to delay it to this point. It is looking really quite good (from specs), much better than when they first announced it.
From the specs, I would describe it as a "UHP-powered G13" (fictional). In other words, a quiet, cool Gxx right between a G11 and a G15. Rated lumens at about the G13 level, same out-of-box contrast, same SXGA resolution.
I find it interesting that on the site you linked to, they describe the G11 as "good for video presentations" and the G3010Z as "For Super Home-theater".
