You may (or may not) know that IMAX has joined Sony and The Discovery Channel to start up a new all 3D cable channel. We've been scrambling to prep 3D content for the channel. So far we've viewed some material on both the new 50" Panasonic plasma and the 50" Samsung LED. If you're looking to purchase either of these I can tell you that the Panasonic has superior picture quality. The 3D is extremely impressive. Colors and contrast are excellent.

That said, for some reason watching 3D on a TV gives me eye strain rather quickly. I find it very uncomfortable. I don't seem to have this problem when watching on a large movie screen. I'd recommend that you watch a good 15+ uninterrupted minutes of 3D imagery on a 3D TV before making your purchase. You don't want to drop $4000 on a TV and then realize you can't stand to watch it in 3D mode.
