LEVEL BEYOND 30?

So, since it doesn't state this i was wondering. Will it be everyone who's 30 starts there and continue, or the smart thing HOtS did, where they take all your xp you earned after max cap and give that to you to. So if you are level 30 now but played 1k games for example, will you end up starting at level 100 and get all the rewards up to that point? HOtS did that, and gave all the rewards and the new level when they updated, honestly it would be smarter to do that. But i doubt they will they want you to play more, but it would be nice to know.
