Will any of my current home theater equipment work with 3DTV?

The short answer is maybe.

Most of our HD and HD-DVR set-tops will support 3D technology.
3DTVs bought after March 2010 are probably compatible. If you have an older model, check with the manufacturer about any possible upgrades.
If you currently have an A/V receiver, it may not have HDMI 3D pass-through technology, which you’ll need to get a full HD 3D picture.
High-speed HDMI cables (10.2 Gbps or higher) should work fine with 3DTVs.
3D DVDs purchased before March 2010 will not display the picture properly on new 3DTVs.
