I think it must have been the pizza I ate last night, because after my "this could almost provoke me into buying the camera and a TV" comment last night, this morning I find I am a bit more rational and have reverted to my previous position on 3D - "No thank you."
Still it is an intriguing looking beast; if you like square boxy-shaped things (and I do own a Honda Element.)
Camcorderinfo notes that Sony is currently vague on the compression system for 3D recording.
One other advantage this camera has over the Panasonic HDC-SDT750 is that you can zoom while in 3D mode (the Panasonic disables zoom with it's add-on 3D lens.)
The Panasonic currently sells for $1,125.00 at B & H. That's $375 less than the projected price of the Sony, but if you're going to buy a camera for the 3D capability, then save your cash for the Sony.

Meanwhile, in budget 3D shooting, GoPro will soon be offering a plastic case called the 3D HERO for holding two of the GoPro Hero cameras and capturing 3D video. The case will cost $90, and you'll need two GoPro HD HERO Cameras -@ Amazon
($259 each). Sync is reportedly possible between the cameras using the multi-pin expansion connector. Precise alignment of the cameras - and syncing the two so that the frames are taken at exactly the same time - is important if you want to get the best quality results; so we'll have to wait and see how well this combination actually works.

And speaking of the Panasonic HDC-SDT750, you can see some hands-on pics at Engdaget: Hands-on with the new Panasonic 3D camcorder and 3D still camera (though they seem to have miss-identified the model number) and you should also check out some reviews.
