Posting this info here since it is the comparison thread and all opinions are welcome.
the majority of 1000/1100 owners here have moved on to other projectors today, a good number went to the RS600. There are many opinions to ask, or better yet, compare yourself. for me it was an easy decision after a few months of this in a stack with a split source.
late 2016, no real use of the P3 filter, no support for UHD, even with SDR WCG.
3D that wasn't great to begin with (x-talk) and 3D lumen output that wasn't close to the 2D lumens.
No manual control of the iris, no built in CMS.
No firmware updates.
banding (now being addressed for the 5000ES many years later)
overcooked reality creation (tempered a bit by the 1100 update but not much)
The annoying horizontal bar that would show up in low IRE content
panel contrast degradation that affected a number of folks that recognized it and had Sony repair it.
I wanted to love this projector when I first got it but the high price and concerns above didn't make sense to keep it. The classified forum and ebay were filled with 1000/1100's this past year.
many of these issues were addressed with the mid-range Sony 4K models, this is clearly where they are putting their effort now. I think the 1000/1100 projector was just too far ahead of it's time for it's own good.
The JVC Z1 is comfortably going to take the VW1100's place at this price point, Sony either wasn't expecting the Z1 or has a less bright '2500ES' lined up at 1/2 the current 5000ES asking price.
