Finalists will be announced Wednesday. If we finish the finalist slates before then we will move up the announcement, but right now we're finishing the TTLB ecosystem categories and need all the time we can get. We may release the names of finalists in sections as the day goes on; it all depends on our progress in finalizing things.
Voting should begin Thursday evening.
In the meantime you can go see a mockup of the voting booth. If you want to stay up to date with our general press releases and notification you can sign up for our Weblog Awards newsletter. If you need to talk you can check out the forums.
PS - To those who have seen us looking at your sites from within our secret work bunker we say "hello." Yes we're checking you out. You may be a finalist; you may not. Check back Wednesday to find out for sure.
Update: The list will be up before midnight Eastern.
