What will happen to the 'Emblems of Frost' in Cataclysm?

I remember reading that the drops of Emblems of Conquest will be changed to Emblems of Triumph, but the thing I wanted to know is what will happen to the Emblems of Frost?

With Emblems of Frost, you can exchange it for the Tier 10 Armor (only lvl 80s at the moment) and thus they farm it everyday but is it gonna be changed to lvl 85 or something? Or are Blizzard going to add a new more powerful emblems to get much more powerful armor for lvl 85? What will happen to the usefulness of Emblems of Frost, I mean if Blizzard are going to add a new armor with better Emblems, will then Emblems of Frost turn out to be a Complete trash item in Cataclysm? Because these Emblems of Frost is really hard to farm since you only can get it from lvl 80 raids by killing the bosses, or get two of these emblems by doing random heroic every day. Maybe the Tier 10 armor will be changed to lvl 85? But if that happened, what would happen to all those players that is currently using/equipping the tier 10 armor?

I've tried looking for this kind of information in google but had no luck with it...
