Yeah this is an interesting and difficult question to answer.
In terms of players, DriveClub will get the most because of it's PS+ option. If it's any good then it would do very well on digital sales (which are obviously not tracked).
I believe Forza Horizon will do very well on XBO.
I believe project cars will do well because of all the platforms its releasing on.
So yeah I'm stuck for an answer to which is going to be the best selling.
