The last paper editions of USGS topographic masp came out in 1973 and 1992.  If you are waiting for the next print edition, you'll be waiting a long time.  Like so many other agencies with information distribution, the USGS topo maps have gone digital.  In 2001 the USGS announced the production of a current, seamless digital National Map.  You can still quadrangle chunks of the National map and download them for free as PDFs (with geospatial extensions for measuring).
