As I said in another thread, the annexation of Austria and/or Bohemia is a serious risk for Bismarck and the assured rise of the Zentrum, Bismarck and his party have strong personal motivations against full annexation of Catholic regions. I think that "Britain will not like!" is a good cover to the real reason "My political enemies will get stronger!"...
It's also a good reason in and of itself because it puts at risk his "baby": unification of Germany under a strong, aristocratic, Prussian-Junker dominated Conservative system in a way that it will be accepted by the international community. Keeping Austria out fulfilled both goals.
