Agreed on all counts except FI... no FI on this one. They should be a step up for the price difference. I think it is more similar to the new Mitsu DLP, but with better placement flexibility and without the 2D-3D conversion or FI. The reviews have been pretty positive (especially the hometheatermag review), really a pick your compromise proposition... 3D (z30000) vs blacks (RS46) vs balanced (HW50es)... I'd say sports for the Sharp as well, but without seeing it in person, I'm not willing to say that without FI. Honestly, my biggest worry with it would be support if Sharp exits the marketplace or goes belly up as a company. For those with modestly sized screens (142" is not modest, zombie), the z30000 looks like a decent alternative to the Sony as a good all-'rounder giving up a little black level for 3D performance and saving a few $ as well. Certainly sounds better than the BenQ if it is bright enough and you want a 1 PJ solution.

I wonder what he'd think about 3D IMAX?
