Dominoes are already falling. Brickhouse Grill, Joe's Crab Shack and Alehouse all built from the ground-up. Tilted Kilt is also new, but not sure if that took over somewhere else. All within the last year, maybe 18 months. Couple new places in Pointe Orlando, too, which has largely managed to transform itself into what PI 2.0 was initially supposed to be (a grouping of mostly upscale restaurant tenants, many of which offer some sort of late-night entertainment, catering to the convention crowd).
To say nothing of D&B, which in and of itself has been a game-changing success.
I don't know that this is on the table, but I-Drive Live is perfectly positioned to take advantage of the always empty Universal Blvd., which links directly to 528 (just 2 miles from I-4). If they can use signage and marketing to convince people coming from the south, including WDW, to use that route, it would alleviate a lot of the traffic problem.
Can't believe I'm defending JT in a DTD thread--there goes my Doom & Gloomer card--but I think he might be onto something here. Sure DTD has been on the table for years, but few if any of the initial plans have or ever will come to fruition. Splitsville seems an obvious response to D&B. If I-Drive Live actually gains traction--a big "if", this is already take two--I wouldn't be shocked to see some sort of response at DTD.
I kind of agree with the FLE as a response to Lego Land rather than WWoHP theory as well...but that's another thread.
