Magic Kingdom's "Wishes" fireworks--are they really replacing it?

I was just reading some comments on a website referring to this being the last year for the "Wishes" fireworks show at Magic Kingdom, and that it will be replaced with a new show next year. I read that it was cast member confirmed and one person even claimed to have seen a preview of the new show and states that it's amazing and will bring tears to your eyes. Has anyone else heard this?? I can't seem to find a reputable source anywhere for this (maybe I'm just using the wrong search terms), but I'm gonna be totally bummed if this was the last year I get to see Wishes!
