It opens March 1st and looks amazing. If you goto the Seaworld.com website there is a link at the bottom of the page.Can't remember the exact web address off the top of my head.
We are waiting to hear some review of it before deciding between the there and the WP option at WDW
ETA: actually, for some reason 3/9 is sticking in my head. Maybe that's the opening day. Either way it is early March
