My “Video Unit” link wasn’t available yesterday when the announcement was first made.
Was able to see it today.
“Linked” my Adsense account with my YouTube account.
Got the confirmation from Google in a few minutes (they do warn that it could take up to 12 hours).
Created my “player”, got the code.
The ads load asynchronously, and they seem quite on target from the other sites I tested so far.
Way to go Google!
