Also, the Galaxy A8 (2018) and its sibling the Galaxy A8s will be demoted into quarterly and other regular security updates respectively.
When it comes to new phones, their start life is not guaranteed yet which is not the same with affordable models. With the brand-new Galaxy A02 and Galaxy M12, their updates will be having quarterly updates. We can also expect by next week, Samsung will announce the M12.
