Well, here's a glimpse of what we'll face further along...
On a side note, looks like we'll be seeing a return of the pigs and parasitic villagers from the first game, too.
That said, the latest update has some other things worth mentioning. Counting the Tutorial dungeon, Uu has plans for the full game to boast six dungeons. Mind you, this doesn't cover anything in-between as the dungeons themselves are technically where you confront big bosses at their individual ends. Looking forward to more info on that, certainly...
