Progression level?

So on the "features" it says that "Outland will be available one month after launch". Now that's all fine and dandy, but will there also be a hard level cap? For example, one could theoretically level a bit over lvl 60 if my memory serves me correctly, even without outland. I think if there was a cap, it'd be great for pvp-ing at lvl 60. If someone's level 64 and someone's 61 it wouldn't be as fun.

Of course, if I'm being ******ed and it has been mentioned that there will be a level cap, I apologize.
