I kinda made the original post as a spur-of-the-moment thing when I read the news that the third part of 4.0.1 had gone onto the background downloader; we're getting very close now. There was a PTR patch this morning which was a small number of minor class changes; give it a week or two more, I reckon, and we're there.
Also, as suggested, I will sticky this thread.
Finally; there have been some rumblings about Reforging making it into 4.0.1. I'm really not sure about that yet, since it was just a short reference on one site, no major announcements or confirmations or anything that I've yet seen.
