Bashiok posted a new update the developers have decided for the Justice Points conversion to be applied to Emblems of Triumph and Emblems of Frost in the upcoming patch 4.0.1. The Justice points have drastically increased to benefit players. The gold per emblem in excess of the soft cap will be lowered down too. – Source
[BLUE]We’ve revised the Justice Points conversion rate for Emblems of Triumph and Emblems of Frost. When the upcoming 4.0.1 patch goes live, these emblems will be converted into 11.58 Justice Points (up from the previously planned 2.75 Justice Points per emblem). Justice Points accrued above the soft cap of 4,000 will be converted to gold at a rate of 47.5 silver per point (down from 2 gold per point) when patch 4.0.3 goes live.
The original explanation thread (http://forums.worldofwarcraft.com/thread.html?topicId=26850245012) and the subsequent conversion math update (http://forums.worldofwarcraft.com/thread.html?topicId=26850245012&sid=1&pageNo=10#184) have been updated to reflect these changes.
The previous conversion rate was intended to devalue Frost and Triumph a bit to discourage some amount of farming and hoarding of points before the conversion, but then we came to the conclusion that no matter what we do people would be farming well above the softcap, and we shouldn’t try to make it more difficult for them to do so.[/BLUE]
