There's indeed a lot of teasing like this going on at WMD, and we continue to get surprises...
There'll be no Ferrari on release though, as others have confirmed, but who knows what might happen down the road if the game sells well, Namco Bandai opens their purse, Ferrari realize they have to be in the game (
) etc..
Nothing would make me happier than seeing Italian race cars in the game - if we eventually get Alfa Romeo and Ferrari (see my avatar!) I'll be in heaven. But, even without marques like these, it still looks like we'll get the most complete, well rounded and fun racing sim/game to date, with a mouth watering car list in any case. Like Snaeper, I choose to not expect anything more.
