Deepest "possible" stacks

[reidardahlen]

Just out of curiosity, where do you think the theoretical treshold for stack size in terms of BB is in a NLHE game, so that all the chips are virtually never going into the middle? Of course there are maniacs who would gladly call a 50X potbet on the flop, but consider a game with about six good/expert players.

For instance, would a $1-2 blind NL game with $1500 stacks play any different than the same game with $3000 stacks?
