It's morbid, but true. If GL doesn't release the OUT during his lifetime, the chances will probably greatly increase after he dies.
An interesting comparison can be drawn with Michael Jackson and his concerts. Despite their (for lack of a better phrase) SHEER AWESOMENESS, MJ never released any of his concerts on VHS or DVD. He was a perfectionist, and felt that the full experience of his concerts can only truly be felt if you are there in the stadium live.
Fast forward to October 2009, 4 months after his death. Sony Pictures puts out "This is It" a documentary made by splicing various REHEARSAL footage for MJ's "This is it" Concerts. MJ, judging from the past, wouldn't have even put the final, complete concert on DVD or Blu Ray. Yet, Sony releases the incomplete rehearsal footage. The perfectionist would have NEVER stood for it, but he was dead, and money is money.
tl;dr, we will get these movies on Blu Ray. It may not be soon, but it will happen. Now we play, the waiting game.

Ah the waiting game sucks, let's play Hungry Hungry Hippos!
