First movie Cars was a success having a budget of $120M this movie have gross only in US $244M and worldwide $455M. The second one is a very successful movie who start on a budget bigger than the first movie $200M and who gross smaller then the first movie is US $191M, but much bigger worldwide $549M (until now) making with the first movie over $1B. Now about Cars 3 ... should definitely be a greater success.
Cars release date was 9 June 2006 (USA), Cars 2 release date was 24 June 2011 (USA). These information make us believe that Cars 3 release date could be somewhere in June 2015 or 2016 (nothing official at this moment).
For Cars 3 the director and the writer should be in my opinion John Lasseter because he is involved in the first two parts and it seems that he's doing a great job. About the cast ... voices can change but the Cars: Mater, Lightning McQueen, Finn McMissile, Holley Shiftwell, Sir Miles Axlerod and Francesco Bernoulli must be in the third part. We promise that Cars 3 trailer will be here as soon as possible, until then we let you enjoy a very interesting featurette about the sound in Cars 2:
