I recently pre-ordered a few movies and noticed that the release date just said TBA until the moment it released. The way I found out that they were ready to watch is that I got an order confirmation that my credit card had been charged. It'd be great to know a couple days ahead of time when it will be released in case I want to invite some friends over. There doesn't seem to be any other benefit to pre-ordering (since the pricing isn't better than buying it on launch day) so this might be a little something to encourage people to pre-order. (Ideally there should be a price benefit to pre-ordering, because otherwise I'm wondering what's the point?)
