You clearly don't want to believe that Tink and friends will be in WDW next year. That's fine. I don't know why you're so dead set against it, but I can tell you with complete and total certainty that WDW is getting her as well. The Disney Fairies is a huge global marketing push for the company, and it will involve both US resorts. There's simply no reason for it not too...and who said they were going to be in Toontown Fair?
And parades and parties are different from meet-n-greet characters, and when it comes to the major ones, both resorts always get both. WDW always gets the more obscure ones as well since DLR doesn't seem very interested in broadening their character collection. WDW has Marie, Clarice, Barbossa, the new Tremaine and Stepsisters and many more characters that DLR either has never had or just stuck in storage until the end of time. So if any new characters are added to the parks, WDW always gets them while DLR is usually shafted.
So if anything, WDW should have the Fairies and it should be iffy for DLR, but it's not. It's a definite go-ahead for both resorts. From what I understand, Tink is being looked over right now to make sure everything is good with her new park duds. I'm not sure where Iridessa, Fawn, Silvermist and Rosetta are in their journeys to the parks, but Tink has certainly progressed quite nicely from what I'm told. It's just a long flight from Pixie Hollow all the way to Walt Disney World.
