Meh. I don't really expect many new surprises. Mob change was very likely to affect drop rates of something (like adding more boar camps, as someone said on the thread) and make it easier to get exploration achievement. Rivenroad may or may not be related to one of the new quests, likely is.
All I expect from this patch that wasn't mentioned is one or two new monster types out there. Given the fact that Goobues are going away on patch 1.23a, the real final boss will only be added on that patch.
