It is limited in the sense that annual production numbers have to be kept below the threshold where more stringent construction legislation would apply. I've read that this is around 1000 cars per year for the European market alone but am not sure how many more they are allowed to make for the US, ROW etc. The supply of coupes to the US market ends with the 2016 model year as it will not meet changes to DOT airbag rules that come into effect for the 2017 model year. The spider is unaffected (I've no idea why) and will still be available to buy.

There are also physical restrictions on how many cars Maserati can build per day plus the number of carbon tubs Adler can make for Alfa.
