Definitely a coincidence. You can’t just slap a game and devkit update together in under a week.
I think my speculation on what might be going on at Funcom in another thread is accurate:
It seems confirmed that a Conan dev team does still exist, but now the question is how many are there and how long are they going to keep working?
Apparently the changed assets in the devkit point toward one feature (tavern patron brawls) being canceled, which is a bad sign, but another feature (dark Dregs) getting more progress, which is a good sign.
