I don't recall Kinkoid ever saying PvP is now a significant source of income. It's just a nice bonus. Main sources of incomes in the current gameplay still are bosses (after you level them, of course) and harem.
That being said, it semes that PvP money reward raise with your classement in ToF. With 6 wins, i make 30000. So, I suppose i make between 100,000 and 150,000 per day with PvP. Not game changing, but nice.
