For finalmecia, the threshold is 63 battle. If you did less than 63 battle per day against her before, you will make more money now (once she is upgraded at lvl 260).
If you were a no life that wake up by night, you'll make less.
That's purely boss speaking. But with the addition of PvP in the mix, you should make more money than before, whatever your playstyle (casual, "normal" or no life).
Also, keep in mind they will add yet other features into the mix, such as leagues/ladders and clans battle, that will make you able to earn more money.
Today's release is only the 1st of 4 big releases that should unfold on the first trimester.
