I agree with Tim here.  There were over 400 bugs fixed / new features
between M2 and M3, which seems like an awful lot of code to be testing all
at once.  It also makes it harder to track down what code caused what error
etc.  Given the size of our community and the rate at which code goes in I
think shorter release cycles would make more sense.

As you say, three months from the M3 would put things right into the
