ULA just announced more details on their next generation launcher: I looks like another major leap in space technology will arrive over the next decade. (It's important to have several kinds of launchers, because you don't want everything to fail when one launcher is temporarily unusable.) Also noteworthy is the extent to which electronics and manufacturing advances are changing things. The microsatellites are becoming more and more capable, which addresses the cost of expanding into space by reducing the weight requirements. Tech is both reducing the cost of launching a kilogram and increasing the capability of a launched kilogram.

Commercial launch of communications and other non-government satellites is already routine. Orbital has various non-government launches and clients already. Orbital also make satellites. SpaceX also has many non-US government launch clients announced, and three recent successful launches with non-NASA customers. The better question is when will there be enough customers to make all the launchers, facilities, etc. viable businesses in the absence of government clients and subsidies.
