What do I need to know about 3D TVs for gaming?

The 3D TVs now coming out all support the HDMI 1.4 (or better) 3D standard, which is what the PS3 and other 3D blu-ray devices support.

So yes, you will be able to mix and match 3D equipment from the player, to the cable, to the TV.

The glasses are not standardized yet, though, so you will likely need to make sure that any extra pairs of glasses you purchase are compatible with your 3D TV.

Game support is spotty - games need to be developed that support it, or be patched to support it. There are many sources for information on what games are currently or will be supported for 3D displays, here is one list from December 2010.
