Are the existing mods (especially TDM - my favourite one) compatible with the new patch?

Ummm... maybe. I suppose it's possible that the new features could have been included without adding the format of the AI files, but unlikely. You'll probably find that existing AIs (ie TDM) will work, but they will generate annoying error Messages and won't use some of the new features.

I'm sure you won't have to wait long for patch-compatible mod updates though: Modders have been waiting to play with this patch for ages and as soon as it's released they'll be on it like hungry wolves=-)
