Hmmmm...
Why should wee have to buy new televisions?
3D versions of movies could simply be sold separate, or on a bonus disc.  (They already do sell 3D DVDs...)

It's not worth buying a new television for watching 3D tv shows.
Wearing 3D glasses a lot would be a turn off.  I may be willing to wear them for an occasional movie, but it is certainly not something I would want to do all the time while watching tv.

So either there is something going over my head with this, or it is just a really cheesy gimmick...
