Hi Cividale - I don't think there will be a scheduled ruling, since the hearing on merits is planned for February, 2012. There may, however, be a settlement offered by VZ depending on their level of desperation to get this started (or avoid an even larger payout required by the arbitration panel).
I'm waiting to see how Exxon and Conocophillips do - one of them is rumoured to be ruled upon in the next month or two. Based on their arbitration rulings, perhaps we can get a sense of what fraction of 3.9 billion we're likely to get should they rule in our favour.
