NASA's new Constellation program has been canceled?

I have just heard that NASA's new constellation program which features the Ares I, Ares V, and the Orion capsule have been canceled as for the reason of which the run on the same type of technology as the space shuttles, which as we know is very expansive. So what NASA is going to do next is to develop new type of technologies, new type of space vehicles, that will for example be able to refuel while in space, or even use beaming up energy from the ground to the space vehicle and so on. And NASA will depend on private space companies such as SpaceX. But with the cancellation of the constellation program many questions arise, on of them is, how much longer will it take NASA to develop those new vehicles? Will NASA return to the moon at 2020? And so on.
