Asus plans to expand its ZenFone Max series with at least two new models next year, the ZenFone Max (M2) and ZenFone Max Pro (M2). Although they've already been certified, if Asus follows the same launch pattern, they shouldn't be announced until early next year.

Apparently, the sequels to the ZenFone Max (M1) and ZenFone Max Pro (M1), which made it to market back in May, have been recently spotted at the Russian EEC certification agency. They have been listed with model numbers ZB633KL and ZB631KL, but that's not really the most important thing about their certification.
