Dirt3 was ok, but it didn't live up to the hype and features pushed out and not corrected by CM.
Just as a couple of examples, lots of cars were shown in their marketing videos were not available in the full game, but as later DLC. There'll be x% more rallying in DiRT3 in their interviews etc, but in reality there were probably less unique stages in the base game than DiRT2, as many were rehashed/reversed etc.
I certainly won't buy until well after release, as this sounds like DiRT3 all over again, cutting features, bigging the game up when in reality being very liberal with the truth, and then using customers as a cash cow for DLC.
Will CM give definitive answers to any of these questions, or will we only find out after release?
What cars will there be?
What tracks/variants?
What events?
What views?
What controllers?
What will be included in the base game?
What will be made available as DLC?
Will you have to buy the same DLC more than once to use it in different event types?
