2 months, with all the problems that have arisen, is not a bad development time. the problem is the story progresses very little
Well, the review + ban took a couple days, but it's still barely 4 renders/day best case scenario. If it ends up being the lower end with ~230 renders, it's worse (~3.7). Even without the issues he's had, he was aiming for an end of the month release anyway. This year is, so far, the worst ever in terms of output/day.
But I agree, the development speed itself has pretty much always taken 2nd place behind the barely existing story progression. Well, atleast for the past ~5 years.
