It's to bad it comes down to how cheap can we make it as opposed how good can it look. Passive 3D is below average at best and is vastly inferior to active 3D. Just a microcosm of what the american consumer is asking for. Not LG's fault I guess, as it's easier to just give them cheap low performance stuff vs educating them on what a better picture is and why it cost's a little more!!
Makes me sad!!!
Late in 2010, we reported on a new line of LG LED TVs that the company was calling Nano TV. The LG nano technology uses an extremely thin film with a printed light dispersion pattern to more evenly distribute light across the screen.
Previously the Nano TVs, consisting of the LW9500 and LW7700 in 60 and 55-inch sizes, were planned to use active shutter glasses for their 3D TV feature. However, LG says that due to the popularly of the company's Cinema 3D products, which use passive polarized glasses, the Nano products will now be produced with the companys FPR technology like the rest of the Cinema 3D line (read a review of the LG LW5600).
The previously announced products were expected to carry THX 3D certification. It's not known whether the move to Cinema 3D passive technology changes that. The current Cinema 3D TVs, including the 55LW5600, are not THX 3D certified.
This move means that the only 2011 LG TVs that will use active shutter glasses are the company's plasma TVs, though an LG representative suggested that the company is also working on a way to integrate FPR with plasma technology.
The use of passive polarized glasses takes away some of the pain of purchasing a 3D TV. The glasses are inexpensive (about $10 or free if you walk out of a 3D theater with them on), so a family can easily get enough for guests and won't worry about replacing broken ones. Passive technology is nearly free of crosstalk and flicker as well; however the technology does reduce the resolution of the 3D image—an issue that will be more apparent on lower-quality video such as cable TV or VOD.
As far as we know, the other features of the Nano TV products remain the same, including the 288 zones of local dimming provided by the full array of LEDs. Also built-in is LG's Smart TV platform which includes a number of streaming media apps and DLNA for accessing locally-stored PC media. The 55- and 60-inch models will use 480Hz refresh processing.
The LG Nano TVs are expected to hit dealers in August.

David, yes and no. Part of it is about price, but part of it is about convenience. Powered active glasses are more expensive (we're back to cost again) but they're also a pain. The batteries go dead, they need to be synced to the TV, many of them are large and ugly, costly to replace when broken and inconvenient when you have a bunch of guests come over. All of the above is why Samsung is also investigating a passive glasses solution, though the Samsung plan uses a hybrid panel that delivers full 1080p to each eye. We'll probably see some at CES this year, but it may be a year or more before they're at decent home theater sizes. Plus, they will likely be very expensive because they place an additional LCD layer over the existing one replacing the LCDs in the glasses.
David, of course it comes down to price. The manufacturers were morons for thinking otherwise from the beginning, and they're still morons for thinking they've painted themselves into a corner now. Rather than simply reduce the markup on active glasses to what they should have been in the first place and take a somewhat smaller profit, they just stratify the market with the added "bonus" that there's no upgrade path between segments.
We're left with a low end solution that opens the door much wider, but suffers horrible technical shortcomings (broadcast content, which cuts one of the legs out from under 3D's whole path to ubiquity), and a high end solution that still suffers from pricing myopia.
