It would also be great if the set was even packed in the box (not counting chase figures) but I'm also guessing that we'll see a weighted distribution like normal series boxes have.
This ratio has been making the rounds on many of the Japanese sites and
NCSX as well, so I'm guessing it is probably pretty close:
Boba Fett (Vintage) = 3/12
Boba Fett (Black & White) = 3/12
Boba Fett (Holiday Special) = 2/12
Boba Fett (Droids) = 2/12
Boba Fett (Mcquarrie) = 1/12
Boba Fett (Mcquarrie/Johnston) = 1/12
