So not to flog a dead horse or anything but I've sent a message to 505 asking about the patch saying...
"Hello I am a big fan of IL2 on the xbox 360 console and would like to enquire about the status of the latest Title Update. The patch was released on the ps3 network late last November. The latest update on the official site and forums was that once the patch was released on ps3 it would be submitted to microsoft. The rumour is the patch was rejected and the game will no longer be supported and the game will remain unpatched. Please can I ask what is 505's stance on the issue and if you any any news on it? Thank you."
...through the contact senction on

I'll post any reply I get and encourage others to do the same.
