Dear Mustang,
Welcome to the board! Lately, due to the uncertainty of the economy and its affect on crowds, Disney's been waiting until about the 30 day mark to put up the hours. I'd expect to see them early next week. However, know that even after the hours come out, there have been a lot of changes after they come out. The good news is with the May hours, those changes have been for the good.
You may want to check some historical hours. I don't have the links handy at work, but I'm sure someone will post them. If you can wait until early next week, you should have what you need. I myself am looking forward to a June visit!
Pat
