Read my message below before commenting on ICC's WC schedule. ICC has done it so that viewers get to seethe big maches(like involving Ind, Aus etc) fall on a weekend. They also make more money doing so. its a win-win situation for icc and viewers.
And coming to what A1 and A2, B1 and B2... means
The marking A1& A2, B1& B2 etc are based on the rakings of the teams. As per the group B Rankings: Srilanka(#1), India(#2), Bangladesh(#3), Bermuda(#4).
Lets see few combinations:
If SriLanka and India qualify for super8 no matter who stands first in the group , Srilanka will be B1 and India will be B2.
If India and Bangladesh Qualify: India will be B2 and Bangladesh will take position of Srilanka: B1
If India & Bermuda qualify: India will be B2 and Bermuda will take position of Srilanka: B1
