maybe he broke his fingers while engaging in an awkward sexual act and is now trying to type with his other extremities - but the results are so awful that he's hiding from us...
or
he's got explosive diarrhea and can't get his mind straight to tell us, cuz it's kinda embarrassing...
or
the internet has died in wherever he is located (moar likely)...
or
his dog pooped on his werk...
or
he's pulling a Kentaro Miura on us and we're all shit outta luck (the rumors from the previous posts must have some fact in them!! there're hints e v e r y w h e r e)
*+edit:
perhaps, just perhaps he wants to round off this update perfectly, so that there wont be a shitstorm that a charracters' nose is too crooked or toe is too big, so he's just taking his goddamn time to give us the best experience. devs know this kind of stuff and many of them are exceedingly stubborn perfectionists... then again, those prior mentioned possibilities sound more exciting
