First results from the PRO350W! Came in today, I installed it over lunch (bracket already in place, proper screen distance & orientation already done, so it was basically plug & play).
In 2d, it looks great - I expected a similar picture to one of the 1610s, and it was a little better. On the 1610s I had to tone down the white to get a good balance with other colors, but this one doesn't seem to have the same problem. The default color configurations are all "warm", so I had to change that, but no biggie. I only had about 15 minutes to play with it, but some things I noticed---
There is no din3 connector. So, there are two options for sync: Use DLP Link (which it does support), or your source must output a sync signal. Obviously 3d sources right now are in short supply, so we'll see how that works out. DLP Link is interesting, though - The bad news right now is that I'm only aware of two shutter glasses manufacturers making DLP link glasses, and the cheapest (xpand 102) are $150. It'll be great not to have external hardware like an IR emitter, but not THAT great
Anyway, I played around with the dlp link settings, and basically it just has on/off and an invert setting (so it's not a problem if your signal has eyes reversed). When the dlp link is turned on, the screen looks noticeably 'washed out' if you're just watching it with no glasses. I believe this is because the nature of the dlp link is a white flash between frames. I'm guessing, but it makes sense that this would have the same effect as shining a light on your screen... However, My bet would be that the DLP link glasses will 'filter out' the white flash, so it shouldn't be an issue. Hopefully I'll have an opportunity to try it out soon, I'm just not looking forward to dropping $150 on a pair of glasses!
Obviously nothing is stopping anyone from connecting a sync signal to their source device. I've got an ATI video card, so no nvidia 3d option for me, but I'm looking forward to seeing bit cauldron's recently announced USB device. The issue with that, however, is that if you've got multiple sources you have to come up with a way to switch them around.
Finally, one last note - I wanted to try to put the projector in 120hz mode, but Windows 7 didn't recognize it (or at least, it recognized it as a generic display device), and doesn't list 120hz as an option (max is 85hz). Hopefully that's just a driver issue related to it being such a new display, but I'll look into it more when I get home.
So in summary, I still feel good about it, since I sold the old setup for more than the new, but they *****REALLY***** could have simplified things a billion times over if they'd just included a din3 port. and I worry about windows setup now, but again I haven't had enough time to even try to fix that, so we'll see.
Oh, as a note, I'm a hobby embedded designer, so I'm thinking it might actually be easy to make a tiny device that sits above the TV and interprets the DLP link signal and emits a standard infared LED signal (or has a din3 connector). I know the standard infared signal is just a square wave, so that would be easy, but does anyone know if the detailed specifications of the DLP Link protocal are listed anywhere? I googled for a while and couldn't find details...
Second note, just read the note above about hdmi 1.4. I can't find anywhere whether this one lists the port as 1.3 or 1.4 - which I would guess might mean it's 1.3. Will try to find out for certain. Meanwhile, I would expect (but not count on) a firmware update to support 1.4 - the difference is mainly in acceptance of different protocols, so it should be possible. And there's always the converter discussed above, though I worry about how that plays into the hdmi standard....
(UPDATE) - 3d is NOT available at any resolution above 1280x720. So that's why I wasn't seeing the 120hz option, it doesn't work at 1280x800.
