I was at the same meeting as your friend. Our host and speaker was Michael O'Gratten, the VP of Disney-MGM Studio Operations (aka the main man). He said there is some new entertainment coming in 2007 & a new attraction coming in 2008.
From several other encounters with him and others high up the food chain Id suspect to see some sort of Narnia attraction and perhaps something to do with Cars and/or Incredibles. But who knows...
We do know for sure that a new "float" will be added to the Disney Stars and Motor Cars parade. the floats will be themed to "Cars" (I know it sounds crazy but yes WDI will them a car to Cars!). You should also be expecting to see some cars from "Cars" in a character meet n' greet sometime soon (dont ask how theyre gonna do that cause i dont know and no one would talk about it).
also I dont know if youve heard but Kim Possible and Ron Stoppable have been making appearences aroung the park as well.
then of course you all know that the Jedi training camp (usually reserved exclusively for stars wars weekends in may) is being tested for permanent placement in the park as well.
