i've been playing arkham city for a good while today and have to say that it is a STUNNER. no, it's not true stereoscopy, but trioviz reprojection, but it works VERY well with the art style...which has a comic book sense to it but modeled in a 3-dimensional world. the ps3 trioviz implementation doesn't completely have the action figure/claymation look or pop of uncharted 3, nor the definition or depth of the nvidia 3dvision pc implementation seen in arkham asylum....but it is a whole lot closer than i thought it would be. also on ps3 in true 720p it is RAZOR SHARP, especially with no anti-aliasing (i know that sounds undesireable but it only adds to the definition in 3d, and the only time you see jaggies is sparsely on batman's cowl around his mouth/chin (not his "bat ears"), but even then i like how clean it looks). the compressed color palette also makes the lack of anti-aliasing a non-factor since the highs and lows of all the objects mostly blend together. neither 360 or ps3 has anti-aliasing this time around btw
another thing that is great about arkham city is that you don't lose ANY visual quality it seems in 3d compared to 2d, where as in uncharted 3 and killzone 3 they have to make some sacrifices with the models, environment, and lighting (moreso kz3 for the last one). it truly looks like a AAA game in 3d without VIRTUALLY any negatives. however there are a few glitches that have popped up, but they are rare.
1. about 25% of the time when the game switches to a pre-rendered cutscene, for half a second one eye will be black and the other will be still the correct frame. i don't know whether this has to do with hard disk fragmentation on the install or not, and it has only happened 4 times total, perhaps out of 20.
2. some higher detail model of buildings "pop-in" when you're gliding around the city but it is VERY infrequent, it has happened only twice over more than a few hours...and again perhaps might be cause by hard disk fragmentation.
3. when looking down what should be a straight plane (like the floor of a building or down a street), the depth will look more like a curve, like everything is going slightly up and down a small hill. it's not that bad but it is something to note. gear of war 3 also has this artifact but slightly worse as it has more depth across the plane of view. arkham city definitely has a LOT of depth too, which was the main thing i was hoping for, and it looks great especially when looking across the city, or down the halls (and when flying and diving). and since it is true 720p on ps3, it doesn't have negative that gears has in side-by-side half-res mode that the further you look "into" the screen, the harder it is to see what's going on. hopefully the 360 will be able to update with framepacking hdmi 1.4 3d and there will be a patch for both games.
overall i say that this game is a must get and it uses 3d VERY effectively...but also due to the art style and content, it can get away with the trioviz implementation a lot easier than other games can. i also very briefly tested it out with different display size settings and set to 10" it look a little bit deeper but not a whole lot when compared to my accurate screen size setting (135") but it did seem preferable. i'll have to look at it again though. also btw, i started playing it in 2d first and it looked really FLAT, like it was begging to be seen in 3d, and was made to be viewed that way. for me it is definitely the only way to play.
