Hmm interesting. Going to level 30 will make for some interesting games!

I believe it's epic only in name...From what I have heard:
1-10: Heroic
11-20: Paragon
21-30: Epic

Of course, it could be a false rumor.

Could be. Of course, if they found a way to extend standard progression to level 30 without breaking the game, I'd be pretty much astonished. I wouldn't bet on Epic Spellcasting being in though. At least not without huge changes.
