I had a chat on the Benq website with a tech last week. I had ordered a w7000 from VA, but it is on backorder at this time. Although, their site did seem to indicate they had it in stock, but that's another story. Anyway, I had an Oct '12 build and a Nov '12 build that I had ordered from Amazon. Both had 1.00 firmware and both had iris malfunctions. I decided for a variety of reasons to order my next one from VA.
Since it is backordered, I decided to chat with Benq and see what they had to say. To get to the point...........the tech said that everything they are now sending out is the w7000+ and has the iris fix.. True??? I don't know, but since I've already returned two, I am hoping that it is.
I doubt this is much help to you futiless and I am still wondering if the "iris fix" with the "+" model is just BS to not lose sales. I agree with you, this is a mess and very confusing.
