I had the same initial reaction, but I think it's because the first section of predictions (his cosmology section) only enumerates things that might be wrong, which makes a strong impression. The predictions that best satisfy my intuition's classifier (not exactly a scientific process) are the ones that suggest an expanding of our current knowledge through the discovery of some new, fundamental thing—like a new piece of quantum mechanics, a new systems-level understanding of neural activity, new life forms that evolve our models of life, etc.
