I have the English early release version of Reamde, and I hadn't even noticed it was littered with errors and atrocious formatting problems. Yeah, there are a couple of/off issues, but apart from that it doesn't seem bad. So... unless it gets a lot worse after about 1/3 of the way in I suspect people are exaggerating wildly.
I hadn't realised the early release was a mistake - I thought it was just progressive thinking
