Do tou think the KC royals will have a promising team next year?

No. They will fire Ned Yost for some other "no name" manager, rely on the same old tired farm clubs offering up mediocre players, and the few talented ones they do have will sign with the Yankees or Red Sox after a couple of years (I will bet Zack Greinke leaves them this off-season), and they will hover around the 100 loss mark for the umpteenth year in a row.
