I'm doing a lot of reading on different projectors, checking reviews, comparisons, and although there are some minor variances between reviewers, the general consensus I'm seeing is the AE8000 offers good-great performance across the board, it doesn't really do anything poorly, but nothing superbly. The JVC or Sony's in that price range offer their own advantages, better blacks, image processing, excellent 2D performance, but as you mentioned, the JVC suffers in 3D performance, and the Sony is about 20-25% more but offers respectable 3D. One thing I find a lot of reviewers leave out is the gaming lag, as this will be a good chunk of my use. The 8000 has acceptable gaming lag, but I haven't found numbers on the JVC or Sony yet.
Admittedly, most of my viewing will be 2D, however, on the occasion I want to game or watch a movie in 3D, I want the experience to be tolerable, from the sounds of the JVC, it would be so poor, that I would never want to use it. Tough decision...
Oh, I only thought in terms of "replicating the movie theater", but now all of a sudden I see that gaming is a good chunk of its use (or did I miss this before). For me personally, this changes the situation BIG TIME, and motion resolution is actually farther down my list of issues than you might think.
But if motion becomes a #1 priority all of a sudden, ATDG is right, you might consider DLP, as it's the best in this regard. This tech also gets you the best brightness typically as well. Compromises however include: possible RBE for a small portion of the population, placement inflexibility that sometimes borders on the comical, older technology that hasn't been known to make significant strides in recent years, loudest (brighter is always louder), lots of moving parts that may or may not lead to "catastrophic" failure, poorer black levels and shadow detail.
Now if it was ME, and I was FOR SURE going to do a lot of gaming, and it had to be on THIS system, I would think long and hard about forgetting the cinema, and going with a big plasma, 65" for the money. You will have the best motion rez, lag is only as slow as it takes an electrical current to excite gas, you will have the best black levels and shadow detail for both movies and gaming that this money can possibly provide you, when I think of gaming I think of someone leaving the unit of for many hours at a time, taking breaks, getting drinks, not watching a 2hr movie straight through no interruption and turning it off. You are probably not considering the expensive costs of bulb replacements, and you are also probably not realize how often they need to be changed. 1K hours is normal. If people are claiming to go well past that, and there are some out there, I bet they have stupidly low FL. I need to go to hi lamp as soon as 800 hrs, if not sooner myself. Oh yeah, then consider this, for best video calibration accuracy, you need to check in on it WAY more frequently than with other displays, and if you're gaming a lot, your cinematic quality will suffer if you're not addressing the compiling hours. The plasma will also be brighter.
I know I like a greater than 40 deg viewing angle, if anything, even greater than that even with 1.78, but if 2.35 I'm not surprised if I'm pushing 50, maybe beyond. Yet for gaming, I can tell you for certain that I like it no bigger than 30 deg, and very likely even significantly smaller than that, perhaps 25ish even. That is a really huge difference between viewing angle preferences that I have. As I mentioned before, you should throw up the pic on the wall, to really know. Yes some games make this more of an issue than others. BTW, around 30 is still right around the full resolution of 1080p, and is still a bigger viewing angle than what 99/100 of anyone else has.
Like I said, that^ is just ME. But, I bet if you tried your games on the local higher end DLP driven theaters, you might think the same thing.
