I haven't been able to find any official notice of a VISA Europe deadline but I did find a copy of a presentation by a VISA Europe tech nerd that says their deadline is December 2012. SInce its not hosted on the VISA Europe site I can't call it authoritative. Honestly, the best you can do is contact VISA Europe to get the answer straight from the horses mouth. I nudged ambal that way on
this thread and he is researching it to get clear on deadlines throughout the world.
