Elite 4 spoiler:
That being said, the game was fantastic. I just beat the champion, and now I still have so much to do, Pokemon to catch. From what I heard, the ending of the game changes after you beat them again. The levels of the Elite 4 are also around level 55-60 first time around.
This was one of the most fun Pokemon games I've ever played, even though it was a little cutscene heavy. I greatly recommend it, and I'm buying it once it comes out on Thursday.
