I'm not sure what constitutes incremental vs HUGE, but I like what I'm seeing.
The pixel shift and price point for the Sony's seem nice, I like that JVC is now including Reon, and motorized shift at the "mid-level". Panny looks to be significantly brighter.
The 2000U was already known to be a quiet PJ, and its neat to see Sony drop the noise floor even further...
Mine is loud-ish, with manual zoom, no Reon, 700 lumens.
I LOVE it, but some of these "incremental" bonuses would be nice.
