What content is due to come out?

Hi
I don't come here to the assetto corsa fourms that often and also I don't play assetto corsa that much either but I was just wondering about content.
What cars are due to be released?
What cars are due for future releases?
The same for tracks too?
Will they be paid dlcs? or free? Or a mixture?

Hopefully I will be able to get some time to try out multiplayer properly but I don't like the idea of having to use teamspeak (can understand why but I just don't like using it) anyways
