I believe the jury will return a DP verdict. The only reason I'll be disappointed (and more) by a LWOP verdict, though, is if even one single juror says afterwards that she/he believed JA's accusations about Travis.
I don't think there is no way anyone on the jury can know the depth of her hatred for Travis or the abuse and torment she inflicted upon him day in and day out for those many months she spent, uninvited, in Mesa. She is guilty of not only murdering Travis physically, but as he said to her on May 26th, 2008, for murdering him on the inside, knowingly, deliberately, maliciously,with relish for no greater reason than she could and it suited her to do so.
JM will make her spend the rest of her life in prison, and he restored Travis' reputation. But beyond that. I'll always believe she murdered Travis to keep her own filthy secret self concealed. That's why I think JM's other magnificent accomplishment is that he did exactly what she feared most: revealed the real Jodi Ann Arias for all to see, including, may it be so, the 12 jurors who will decide whether or not she's deserving of mercy.
