Avatar On 3D Blu-Ray To Be A Reality Soon
The full version of Avatar in Blu-ray has not been available at stores till now. However, that is going to change soon as from October, people in the US and UK would be able to get their copy of the 3D BD Blu-ray version in 2 discs.
Right now the version that comes is not the extended version of the movie which can be expected to be available in a few years from now. That should also come in two discs with the main film on one disc and supplementary in other.
One can view some clips of the official FB page for James Cameron.
