Similar "What's Next" presentations at Disneyland have been used for updates on things in progress and to announce small little things (e.g., tags to World of Color). In that vein, I would guess that the "What's Next?" part will be mainly 7 Dwarfs Mine Train, Maybe the Grand Floridan DVC will be discussed, and perhaps the restaurant upgrades (California Grill, for example). Perhaps we'll hear about new MK parade(s) and new DHS show(s). But I'd be surprised if there's a big announcement, because that would take the thunder away from all the stuff that just opened (FLE and new Test Track), which is where they want most of the press coverage.
