There aren't many new components. The tech in the Orion capsule is new, but the capsule design is very similar to previous capsules (aerodynamics don't change).

There aren't many new components. The tech in the Orion capsule is new, but the capsule design is very similar to previous capsules (aerodynamics don't change). All the rest is basically re-used tech from the shuttle. I may be wrong in this case about the upper stage. I don't know what they plan on using for those engines. If they're new engines (which I haven't heard of development regarding them), then that could be interesting, but they're likely reused OM engines from the shuttle or something like that.
