Yeah, the emails are pretty incriminating but google will continue to blur the line between java source code (which is free) and Java APIs(which are licensed). Oracle will argue they copied the code without paying for it.
Probably the best and most expensive lawyers in the country will turn this into an exhaustive mental chess match.
It would be amusing if Oracle wins and it backfires on them, with IBM sitting around saying, "Nice SQL database you got there...shame if something happens to it..."
Heck, the software industry is pretty much built on people ripping off each other's APIs and interfaces in some form or fashion.
