We have two apps in "waiting for review" - one is waiting from 9th October, 2nd one from 10th October. But is the same time some simple reviews of another app with just assets (header, search results) went through review in two days. I went thru "Request Expedide Review" for both, since one is for event that will start next weekend - this is crazy, seriously, Google Play Store took 3 days for one app, but a small game with is 2nd one is also still in review.
