Scott Joseph (arguably Orlando's most prominent restaurant critic) says Morimoto, STK steakhouse, and the Edison might be coming to DTD:

Joseph usually focuses more on downtown/Winter Park, but he seems fairly confident on STK, willing to take his word others are in negotiation.
The Edison looks like fanboi kryptonite, will pull a lot of AdvClub fans. I don't see a market for the other two, tho. Won't mesh well with the stroller-pushing, well-done flank steak crowd. And I still have to ask, how does PI alone support 7 or 8 restaurants when the existing 3 rarely have waits outside peak seasons?
