As Da Infamous Rapid Fire already stated in his post DX has been given to two testers.
Here are a few unconfirmed DX rumors:
1. Once the DX power is used, you lose it.
2. If you have two DX’s and you “use the process” once, you will lose DX. If you do it again, you’ll lose the other.
3. Asked “Are you going to sell DX” a tester replied no, because “I am spending the power”.
So… Any guesses?
