That sounds really wonderful. Comment rot is a bad, bad thing, but if it takes a few more days to work out the notifications, maybe waiting would be a good idea.
Personally, I am fine with beta, bugs and a bit of downtime. We know why it is happening. In short: if the site is broken, you fix it and we're all happy...
Good luck with it, I hope it is going to work out well and doesn't break the Interwebs. (And yay for getting tracking and especially tags fixed, I hope they are in this update too!)
