Hi Greg,
I think this is one of the 64,000 dollar questions on the forum at present. However, I doubt that a shootout will resolve much. From past experience, I would guess that the Sim2 is slightly less bright but the 6000hr lamp life and probably still with a more 'romantic' colour balance. All the ergonomic issues are still there eg Marantz sealed box, quieter, but industrial looking. Sim2 with some light spill from the bottom, more noisy but with a smaller, more sexy looking case. As for overall picture quality, my guess is that there will be little to choose between these pj's and the features will determine choice as much as anything. Lets wait and see,
Best Wishes,
Paul H
