Hnng, I really need to reinstall Dying Light at some point.
I can't say the new game is completely action-based, but it has more of that element and real-time than the previous game. However, what makes Final Fantasy and RPG different from other games is that the players have the ability to choose weapons, capabilities, and magic to be stratgetic-minded, so while the new game has more real-time element, it will also maintain that strategy building element, balancing these two factors perfectly to enhance the gaming experience.
Hopefully we'll see some more gameplay in the near future, particularly relating to the Limit Break system. I wouldn't expect a release date until E3 2016/17.
PS. Don't level Aerith.
