Does anyone know if there is going to be different release coming soon of the Wizard Of Oz, and if so, when?

Not that I know of. But the present DVD edition is already good.

Already being discussed here.

Well I clicked there but I still can't find where anybody wrote if it is going to have another release and when???

It isn't likely, dude. I think that is pretty apparent from what is written in that thread. As it stands the current version IS a wonderful SE release over the original MGM DVD. At its current price point ~$13, you should be happy for all the extras it has. I can't think of more that could be added save an Ebert-type commentary....
