I'd be just as happy as the next man to see this go to court, but that's a pretty weak announcement. Completely anonymous sources, and almost no commentary on what they actually said about a lawsuit.
You honestly can't blame Adobe for wanting to bring suit. After all, if they win, they might get Flash on the iPhone; if they lose, they end up essentially no worse off than they are now. I'd like to see how this plays out just for curiosity's sake, myself.
