Think we'll get an update by the end of the month or nah?
I don't want to be that one guy who's spreading doom and gloom around, but this sort of inactivity from the dev could be the sign of only one of two things:
1: The dev is working like crazy on the game and is going to surprise us with a massive update nobody saw coming (highly unlikely, as the only known dev to do this sort of stuff and go the distance until the very end is Grimhelm).
2: The dev is burnt out as he realized that he bit off way more than he can chew and so he just sort of gave up in the end. In that case we can consider this game more or less abandoned (he most likely will at some point show up to say that he either has some issue with hard to deal with bugs during the development or some personal life issues (if he hasn't already), the result will be the indefinite delay of the new update). This is a far more likely scenario, and is the most common one with over 90% of western H game developers (with those that don't continue to milk the dead donkey on purpose at the very least).
All that said, i am totally open to being pleasantly surprised so take my predictions with a grain of salt.
