we've been going to WDW every year since 96' and the pattern has pretty well always been that disney releases the park hours about 2-3 months beforehand with it usually being closer to the 2 month mark...you should expect to see hours for may released any time now, most likely at the beginning of march...you can also get a pretty good idea of what the park hours will be by checking the historical park hours on the main page of this site...
