You still get exp from killing monsters (but reduced), and there are leve's / FATES / EXP Dungeons / Dungeons / tons of quests whatever that new behesty hamlet thing is called (not the fate, thought it was something else Yoshida mentioned in an interview).

I'm hoping they don't try to solve all of leveling up on quests, I'm worried it may lead to some unimaginative quest - would prefer to see some unique quests with interesting elements (can have lots of quests and unique quests intermixed, just hope they don't give up the later for the first).
