Elves may have power and probly lots of people playing them, but elves are mostly turtlers. By the time they reach endgame, and they become really powerful, they will have the disadvantage of having a late start.
It will most likely be the humans who have the best shot of world domination, since they really are the standard race who have a fairly good economy and probly the most advanced of the 3 races (except elves maybe).
