The expert to turn to in cases like this is Florian Mueller. While everybody else insisted the Alsup ruling was a slam dunk for Google and would settle API copyrightability once and for all, Mueller insisted that Oracle would win on appeal -- and they did.
He points out that the justices have been asking some really pointed questions of Google since you made this post, questions which suggest that they don't buy Google's crap for a second and they think Google is trying to pull a fast one.
The law is pretty unambiguous that Google is liable for copyright infringement. Just because techies thought the law didn't work the way it does for decades doesn't actually change anything.
