There are quite a few projectors out there now that support certain 3D formats, particularly Nvidia 3D vision, but none I've seen yet that support the frame stacking Blu-Ray standard (anyone know of any?). May not be a big deal depending on what you watch on it. What do you usually watch on your current one: gaming, movies, TV?

In my opinion, there's not enough content on TV to justify the purchase unless you need to buy something anyway. If you have a working projector, I'd probably wait one more generation. You should then be able to find some projectors that handle the full Blu-Ray spec, plus have more on TV to watch than just limited content on ESPN 3D.
