BD 3-D Spec. We know it's here. But what is it?

[whbinder]

There are a plethora of articles here and elsewhere that say the Blu-ray 3-D spec has arrived. The articles always list some of the features. But the actual spec doesn't seem to be available to the public yet.

Now that CES has arrived, each manufacturer is also putting out lots of hype, but no specifics on tech. And there's a lot of misinformation on all sides.

So... what is it? And please - not to be rude - but I'm looking for specifics and facts, not things that have been kind of generally agreed upon on these forums.

- 120/240 Hz. This "seems" to be the way most of the annoucnements are inferring this will work. Implying the glasses will studder to pick up the sub frames. Sony for example mentions that Motionflow (their version of 120Hz) is integral to the system. If it's not true, then where are the two separate 1080p signals coming from.

- HDMI 1.4. Is it required or not? There are claims that the PS3 can support 3-D and that some Mitsubishi and Panasonic players can do 3-D without it.

- Along those lines, are there 2 version of 3-D? There's lots of discussion of this, but I've yet to see any specifics. By two versions, I mean a version which can go over existing systems with an adapter and one that can only work on 3-D sets.

- Is it agnostic or not. Panasonic claims plasma is the only way to go despite Sony etc announcing LCD sets

OK, and here's the kicker. I'm using Sony for this example, but they're not alone. You can go to a Sony Store to see 3-D in action. If you go down there, they are using a PS3 and a current Bravia set with polarized glasses. (Forgot the model number, but it's not a LX900, HX900 or HX800). I assume they have an advance copy of the promised firmware update for PS3.

Now, two of the announced TVs for 2010 from Sony are labeled 3-D ready. It appears this existing XBR is "3-D ready". So what's the difference?

Further, if you go to the Sony site, they talk about the dawn of 3-D coming with their 2010 models and then say you can see it in action today with existing models. What?

Now of course the guys at the store, don't really know much except what your average store clerk knows. But this is existing technology. What's so special about the upcoming 3-D TVs that is different than the existing sets.

In other words, what makes the LX900 different than the existing XBR9? (Sorry for the Sony specificity here). Can someone please post an actual link to what "exactly" the new 3-D TVs are, and what the 3-D spec is, and

If I buy Cloudy with a Chance of Meatballs, run it from my PS3 with firmware upgrade to a current XBR, what specifically will be different than if I use a LX900 and a 3-D Blu-ray player.

Not intending to be a dick. There is just a lot of hype over very expensive equipment with absolutely no explanation of what it is.

In contrast, when Blu-ray came out. There was all the "hype" that said it was six times better than DVD and looked great and blah, blah, blah. But if you were curious. You could find out that specifically that meant it could do 1080p signals and uncompressed audio and supported java, etc. So far, I haven't seen one single spec.

Whew. OK, sorry for the rant. Any links to specifics on this?
