Apparently not. But I don't mind, the movie is gorgeous in 2D, and great in any format. (That said, I did spring for a Blu-Ray player just in anticipation of "Up." November 10 can't get here soon enough!!)
I'm not sure about Up's DVD release. Recently with My Bloody Valentine 3D's DVD release there was an edition released in a 3D format for home television. The 3D format on DVD is pretty good but not as good as the Real D techonology we see in theaters.
