We will get an opinion from the Advocate General on the 17th December. In around 80% of cases, the judges do follow this, and the actual ruling will be given in the early part of next year.Hopefully the Advocate General is able to see that the gateway theory is a product of certain peoples imagination and has nothing to do with reality, that the health risks are only applicable to certain peoples "smoking-robots" and that dying babies ... well ... is a good sign that they don't have many real arguments to present.
Totally Wicked have published a guide to the process here, and I also recommend following Clive Bates' post on the case which seems to be updated as we're moving along.
UPDATE: Totally Wicked also published a press release on the case today. You can read it here.
