The basic mblock code will indeed be in release 3.1.  However, as you
mention, the modified USRP code to take advantage of it will not be
ready. Other 'convenience' code to pass data back and forth between
gr_blocks and mblocks will not be complete either.  So it will be useful
for experimentation to learn how mblocks function, but not suitable for
use with the USRP until 3.2 release.

Of course, all the code is available in the development trunk for anyone
to use (once it gets merged from the developer branches.)
