A few weeks back, I warned potential Blu-ray and HDTV buyers to hold off because 3D HDTV is coming. Considering the buzz around Avatar, your inability to wait means no watching Cameron’s epic in 3D at home, which means IMAX-sized buyer’s remorse because you couldn’t wait for 3D-enabled (HDMI 1.4-equipped) gear, which is due to arrive next year.

We just got confirmation on that. LG told a bunch of Korean reporters it’ll have its 3D HDTVs out in the second half of 2010. The company predicts robust sales, estimating it’ll sell 400,000 3D HDTVs in 2010 (out of an expected 25 million total HDTVs worldwide) and 3.4 million in 2011. Sony says half the HDTVs it will sell in 2013 will be 3D.

But what about the glasses? Keep reading if you think they’re a 3D deal-breaker.
