All the above really applies to 1080p as well. If someone hasn't got into 2.35:1 yet but wants to, I think they should start without a lens and see how they like it.
There is some truth to what you are saying, but it is one thing to talk about a theoretical "need" vs. what people actually prefer. We have certainly seen shootouts between identical projectors, one zoomed and one using an anamorphic lens. Every time the image with the lens wins out when it comes to which image is preferred, mainly due to the higher pixel density and greater brightness that a lens affords. And I would disagree strongly with you that brightness is no longer really an issue, especially when considering 3D. I would agree that brightness is becoming less
of an issue, though. Even if every projector was throwing out 3000 calibrated lumens, people will always prefer a brighter image over a dimmer one (without getting ridiculous, of course, like staring into the sun
Your suggestion that people try out zoom first to see how they like it is a good one. We are pretty confident that many - if not most - of those people will eventually opt to add on a lens. The AVS Constant Height Forum is full of people who testify to exactly that. Lots of them complain about how they can still see the black bars on the wall. There is also the fact that the vast majority of consumers out there will never put black velvet on their walls to solve this problem (or even understand it, for that matter). Remember, the CineVista is designed for the general public as well as enthusiasts / hobbyists. Sometimes we on the Forum think of ourselves as typical, but the truth is that almost any consumer would be "blown away" by an anamorphic projection system and would never notice chromatic aberration or go through the trouble of pasting black velvet to their walls. They are wanting and paying for an experience, not a system to be tweaked and analyzed.
To make a further point about zoom. What will the average consumer make of the fact that when they go back to the DVD / Blu-ray menu suddenly a large part of the image is falling onto the wall? If they have black velvet up, the menu options will be swallowed up and hard to read. Of course, they can always turn off the autozoom feature, but I just can't imagine people having the patience to have it switch back and forth (every autozoom feature I have seen takes its sweet time switching back and forth between 16:9 and 2.35:1). Most people would just get confused and throw up their hands. It is true that menus are an issue with anamorphic lenses as well, but there is an easy, simple fix - simply turn off the vertical stretch scaling with the push of one button. Much simpler than messing with zoom settings.
Lastly, projectors with auto-irises pose a particular black bar problem, as the "blackness" of the letterbox bars varies with picture content.
