It seems like the top 2 lines will be (and they are interchangeable between what the 1st and 2nd lines are).
One line will have JVR playing on the left side, centered by Giroux and Jagr flanking the right side.
The other line will have Voracek playing left wing with Briere centering and Simmonds playing on the right side.
