Wow...
Well theres some thats planned, and some that are roumered, but i think Tommorwoland is gonna have some new stuff, (meaning Rehabs, and new attractions to fill Timekeeper spot, and possibly The carousle of progress)
and at epcot, they will have there 25th aniversery, which means ( i think) that the living seas will be re themed to have a nemo attraction, then Wonders of life, and maybe Universe of energy will close (Wonders of life is already closed) and some major renivation on world showcase ( or so im told)
some of the info may be unofficial, and wrong, but i think this is what there planning
