So far the variety of bestiary is large enough.
And personally I would prefer to stay unspoiled for the roadmap of game development.
If dev wishes to keep certain updates secret for improved gameplay value, then in my opinion we should wait for it.
Maybe there is werewolves, mayhe there's not. Would be quite anticlimatic if it was completely revealed before the update release.
Things are more interesting if they are more secretive.😍
