There will be a new, persistent rating system that should keep top-rated players facing other top-rated players, regardless of the bracket in which their current team sits. We'll have more information to come on this soon. -- Zarhym (Blizzard)

They've also apparently backed off the stockpiled honor reset and compromised by making level 80 honor gear cost so much honor that even if you stockpile you'll only get maybe one piece out of it. No details yet on the math there. :P
