Not much is being said, but this is from today's WDW Park Update secion on mouseplanet.com:
As we already knew, T-Rex: A Prehistoric Family Adventure will open this fall. Note that it's now just "T-Rex," and not "T-Rex Cafe." The restaurant featuring life-size animated dinosaurs, geysers, waterfalls and a fossil dig site is located just outside the eastern entrance to Pleasure Island, and will serve pizzas, pastas, seafood and more.
