As I understand it that is currently waiting on the message-passing functionality (which is putting the main functionality of mblocks into the standard gnuradio block API). I would imagine it will actually show up with/after the switch to the VRT format (vs. the current raw ethernet frames + thin custom header). In the meantime, if you need the information you could create a custom usrp2 source block which saved the metadata somewhere. Not for the faint of heart perhaps, but certainly doable. Then the real question becomes what you want to do with the metadata (e.g. do you just want to use it in the source block, or do you want to pass it along to the subsequent block(s)).
