How long should I wait to get Curious Case of Benjamin Button

[Idioteque...]

Loved the movie and thought the transfer was awesome but I'm not ready to buy it because of the lack of features on the blu ray and I have this feeling that there's a longer cut being awaited to be released. I know that when I bought No Country For Old Men in January, the announcement of the special edition was announced. I still have not opened it and am waiting to sell it so I can buy the SE, I don't want to take that risk with BB. It's an excellent movie and I want to see it the best format as possible. I know a lot was cut out and I feel the film could benefit from more footage.
