Have a Corsair list from Imperial Armour 11 that you want updated to 6th edition? Well, it looks like everyone will have wait a little while longer. Forgeworld has a lot on its plate right now, and they are very upfront about when they will be updating their books. Below is Forgeworld's response to the question.
The Corsair list in Imperial Armour 11 will be updated, however it does require a significant over haul to bring it in line with 6th Edition and the latest Eldar codex. So, what this means is it will be a while yet before this is updated as a PDF release. Any 2nd edition version of IA 11 would be a few years away from being carried out.
