The lists aren't out yet. As Lee says, most "Big Game" parties are invitation only. The game rivals some of the biggest convention in crowd numbers. I assume crowds are okay for you since you are leaving the comfort of your own home to come here.
If you aren't invited to a party, the next best bet is a big bar. Then a nice sports book. The better they are, the more camping out you need to do. The LVH, Ballys, and Caesars sports books are usually covered by local news to show the crowds. Sports bars on the strip such as Blondies and Le Burger Brassiere will probably be wall to wall people.
I think that I would set up a plan to check out a few restaurants that serve drinks such as Margaritaville. If they are wide open scope out bars near sports books, then sports books, and keep moving up the ladder until you find your comfort zone.
Even as you head off of the strip, the local bars should have pretty big crowds. Good seats and good service might be difficult.
Keep checking back. I'll post what I find.
