It shouldn't come as a surprise that there will be many more "Transformers" films to come in the upcoming years. Even without the Hasbro president being so keen on announcing them a day before at an event in Cannes.
As these films have made a boat load of money throughout the years and the newer movie markets of Asia and Latin America are getting even more interested in what American blockbusters can offer to their regions and economies. Such as easy and passive entertainment, while also the ability to advertise their companies, brands, lands and talent through them.
Though, this kind of announcement should be taken more as targeted message towards the company's stock holders, than for the die-hard Optimus Prime fans out there. Because as long as these films keep on making multi million dollar earnings at the box office and also through merchandising. The Hasbro stock will be considered for a very long time one of more lucrative stock options to hold and if anyone doesn't think of announcements like this in such ways. Should take a few moments of their time and check below the stock activity of the last 5 days for Hasbro corporation.
