I love how people try to say that 3d is on its way out JUST because they do not have a 3d tv. It's not on it's way out - not even close. Maybe your local best buy doesn't have many that they are currently selling but as a tech rep and someone who buys and sales items like this I can honestly say that half of the new tvs that have come out this year (or more) DO have the 3d feature. Maybe the sony at target (that's on sale) doesn't have 3d, but it's also old technology which is the reason it is on sale.The "shutter lenses" only pertain to ACTIVE 3d tvs, not PASSIVE. Passive 3d uses glasses just like the one's at the movie theatre. At first only LG, Vizio, and Panasonic sold passive 3d. But now Sony, Samsung, Sharp, etc, have also jumped on the Passive 3d bandwagon.
I currently play 3d games and movies on my playstation 3 and my LG passive 3d tv. It's gorgeous. I got my tv on sale at a very reasonable price online. I just bought my dad a 55" LED LG 3D TV from Dell.com (now out of stock) for $760.00 -- we set it up yesterday and watched Jurassic Park 3d, it was awesome. The prices of 3d tvs are starting to drop due to the fact that the concept is no longer "new." Because of these price drops you will see an increase in 3d tv buyers.
Also, the future of gaming is going 3d. Currently the ps3 is 3d compatible and Nintendo released the 3ds. At the recent gaming conference sony pushed the new ps4 (playstation 4), that like it's predecessor, allows the owner to watch 3d movies and play 3d games. Nintendo announced that they will be releasing 3d games for their Wii U. Also, Microsoft has recently announced that the new Xbox One will also support 3d technology.
But you guys are so right, 3d is a passing fad, right?
