Sopranos Death Pool?

I haven't seen any of the remaining Sopranos episodes this season and have no spoiler information, but the timing of this announcement sure is curious, especially given the previews for Sunday's episode. True, the previews are notoriously deceptive, but if by some chance Adriana sleeps with the fishes this week, I can imagine the HBO brass is a bit miffed by the NBC announcement. Someone may wake up next to a horse's head.
