I haven't heard about this, but it isn't so crazy. Cargo will probably go in separate disposable rockets, like most satellites do these days.
For humans, capsules are a good option because they are more robust.
The thing that we will miss out on is bringing cargo back down from space. The shuttle is designed to be able to bring satellites back. AFAIK, there is no other solution that can currently do that, but that option never seems to get exercised anyway (although they are bringing back 3.5 tons of rubbish at the moment).
Edit: I forgot to mention that the shuttle is way cooler than these options
