From news article by Michael Kiefer, today in The Republic/azcentral.com:
It's up in the air if Maricopa County Attorney Bill Montgomery will retry the penalty phase or negotiate a plea with Arias's lawyers for a life sentence.

As of now, he will go forward (for show, and better bargaining position I'm assuming) and make the decision to settle later, depending on the proffered arrangements.
Also reported, the July 18th trail date will likely be moved back, because Willmott has a conflict with the date.
As I stated earlier, I think the best solution for everyone - family, court, taxpayers, and those of us trapped in the mind-numbing frustrating morass of the trial -- is to let the judge decide on the penalty. Arias's time behind bars will be the same, no matter what sentence she gets: there's no parole in Arizona if she gets 25 to life; women murderers don't get executed in Arizona (not for the last 80 years); LWOP will equal the same incarceration time as the previous two.
So where's the incentive to proceed? The news article lists numerous other reasons not to. Really, isn't it better to settle it without trial, and move on?
