^ Emphatically this.

Like many people I stockpiled pyrium ore in the event epic gems would be prospectable. But I also took into account that JCs would need the patterns to make the cuts so I have been hoarding my JC daily tokens for several months now. I assume that Blizzard will likely just add recipe cuts for epic gems in 4.3 like they did for the upgraded pvp recipes in 4.2. However, this assumes that they will follow the model they used in wotlk which they are obviously willing to deviate from.

It is possible that they will make cuts rewarded somehow through a raid reputation for the Dragon Soul raid, but this falls into the trap Basil mentioned where PVPers are forced to raid which is against their intended design.

It is also possible that their will be a second tier of JC currency available through new dailies, but then that goes against the currency streamlining process that was implemented in cataclysm.

Personally, I am cautiously optimistic about JC profitability in 4.3. And on the bright side of things, I don't think I will run out of pyrite bars for my truegold xmutes anytime soon :)
