Mounts to be usable on water!

During BlizzCon, Blizzard surprised the audience by responded to the question of when mounts will be usable in dungeons. One of the annoying things in the game is times when you're trying to cross a river or lake, only to get dismounted and have to summon your mount again after you cross.
