My prediction is that MK's lawyers will stretch out the process as long as possible. They will ask for a change of venue (which I believe could be granted), psychological examinations and anything else they can think of in the way of delays that a judge has to grant. And then MK will decide to hire a new legal team and start the delays all over again. I think we are looking at a year at the very least and probably more before this goes to trial...if it does.
Only at the end of this legal maneuvering will a plea deal be considered. Unless it's a very sweet deal, I'm not sure MK will accept. She may prefer to sit in court and watch her defense team skewer witnesses for the prosecution, including her son, friend RR and her ex, among others. She may honestly hold the delusion that a jury will pull an OJ or a Casey Anthony and acquit her.
Throughout this process, there will be carefully crafted "image improvement" stories planted in the press.
All JMO, MOO and hopefully wrong.
