H.264 is already superior to VP8. I see no reason to suspect that this situation will change.
EDIT: I mean to say, H.264 implementations (particularly x264) are way, way, way out in front of VP8, so even as the H.264 standard is better, the actual facts on the ground are even more so. The only reason to use VP8 (and let me be clear: I think this is a perfectly legitimate reason) is political.
