By all accounts, there will be many witnesses the defense can now call, and the denial of the 72-hour time window means that the defense can bring in any saxual activity that occured around the times of her hospitalization - and that can be used to perhaps establish a pattern of behavior.
I really doubt that the stubborn prosecutor will back down and drop the charges, but he ought to. It now looks to be a very long - expansive and expensive - trial. Someone is going to look very bad at the end of any trial, and from the way things are stacking up, it ain't going to be Kobe. His career and marriage, stained as they are, will go on. If the prosecutor presses on and loses, HIS career will be over.
