US Topo project objectives are continuous product improvement, a rapid refresh cycle, and automated production using currently best available data. It is therefore unlikely there will ever be a final and ultimate product.
These goals are different than traditional mapping programs, which made each map one time but went to great effort and expense to make each one as nearly perfect as possible at a particular point in time.
USGS is committed to a third 3-year cycle of US Topo, which will extend the project to at least the end of 2018 with the current PDF product.
