I only heard of one possible one around 18 months ago about the possibility of a no themed line but as far as I know, that isn't going to happen. Lee could probably answer this though.
But from what I understand, the modern concept of Everest doesn't seem to be able to be much grander than its current incarnation. But it does show that Imagineering (and management) is making a 180 degree turn.
I should also note that if Disney had made Sky Captian (though they did not), Everest would have fitted perfectly in Tommorowland at the Magic Kingdom. The ride could have remained the exact same as it is now and it would still fit in.
