I don't see any races being added in the near future with the massive construction taking place or scheduled to take place. I think the Star Wars would a top grossing, top selling guarantee and then the tie in with a C2C. Seems that DL struggles, not much but somewhat because of the cost. So to add a mega cash cow in WDW and have those same people go to DL the same year is a no brainer.
But I don't see if happening in May. Already too much going on with SWW. Plus, I read people saying it would be okay to run, it's hot but it's been hot for ToT too. There's always a chance of hot or hotter than usual weather in October. But the chance in May for hot as heck weather is pretty much a guarantee. And because of this I think it would have to be a night, Fall race. Plus, it's Star Wars, it's gotta be under the stars.
I do like the idea of the Pixar race weekend. That's cool. I'm on the fence about Avatar themed race. Never seen the movie, will definitely go to the park, but I don't think that generates anywhere near the hoopla of other races. But like someone said, ToT and EE at not really tied into movie or current things, so. Disney could easily go either way.
I really like the idea of a race involving the water parks. I mean, how cool would it be to COOL down at an after party there. But with libility and hours, etc, don't see that one ever happening. Maybe a 1 mile fun run and doubt that.
I believe that ToT needs to come back after construction. Very popular, cool race, great after party. It's just dependant on if something is put in that spot.
But as we all know, if Disney puts out any new races we'll all sign up and still ask for more races. Our paychecks should just go straigh to them! Have fun.
