After the shuttles, we won't be seeing any (overly) reusable craft for quite some time. They are just not good enough (saftey risks. Safer to make something new than repeatly patch up holes in something old). This is where the Crew Exploration Vehicle comes in. Its gonna be basicly similar to the Russian Soyuz, only more modern. NASA also plans to use it in a similar style to the Saturns, using it as a Comand Module to the Moon and eventually Mars.
A little while ago, the Nasa/airforce X projects included several space vehicles, such as the CRV, X-33 and eventually X-37. The project got scrapped however. Apparently, the CRV should be making a reapperance though.
