With git 1.8.2+ (March 2013), you can define a submodule which will reflect the latest commit of a given branch.
See "git submodule tracking latest".

It means this would be enough to update a submodule to the latest of a branch:

# --remote will also fetch and ensure that
# the latest commit from the branch is used
git submodule update --remote

See git repo commit 06b1ab for more on the --remote option.

To recap:

• For a new submodule (which must follow a branch):

  git submodule add -b [branch] [URL] [DirectoryName]
  

• For an existing submodule that you now want it to follow a branch:
  See also git repo commit b92892, for transforming a git submodule into one which follows a branch.
  All you need to do is:

  git config -f .gitmodules submodule.<path>.branch <branch>
