If the use of the 8700's dynamic iris could multiply its native contrast by 20, then maybe their slightly improved iris on the 61000 can multiply it by 25. Just a thought.
Also, I believe the 21000 and 31000 were specified as having 24,000:1 native contrast ratios, which would mean a difference in contrast between the consumer and pro models for the first time.
Yeah, I also read the 31000 has about 25,000:1 and the 61000 has 40,000:1 native contrast. Epson made a huge deal of advertising the 61000 as the FIRST PROJECTOR to reach 1,000,000:1 contrast with dynamic iris. There were rumors that in reality they weren't able to reach their claim - thus the need for much more tweaking and a delay of a year in releasing the unit. It would prove quite embarrassing after making such a big deal about that claim if it turned out it wasn't true.
Other sources claimed the delay was due to a problem obtaining the necessary materials for chip production. Another source claimed the delay was due to many chips after manufacturing that were not within acceptable tolerances. So, who knows.
The thing is with dynamic contrast ratios on a projector at 1,000,000:1, you better have a TOTALLY dark room without ANY ambient light anywhere. Even a small LED light from a component in the room will knock that 1,000,000:1 down to maybe 10,000:1 really fast. Once you get over a certain contrast ratio, I'm not sure it makes much difference anymore - especially on front projectors.
If the Epson has a solid native contrast of 40,000-50,000:1 with the iris producing a dynamic contrast at least 10x that amount, that's good enough for me. Just as important are color accuracy, brightness, shadow detail, and motion. From what I have read, the Epson is very strong in those areas. Another plus is the customer service and warranty that Epson provides. That's why I"m trying to wait this out. There is the potential for a very good projector here.
