According to Asus' past announcement, Zenfones will no longer be budget segment phones. And 2nd gen Max (M) series prove that. So I expect Zenfone 6 with higher level components than its competitors but with a higher pricing. So +400€ price tag won't be surprising for me. I hope ZenUI will be acting better with the new release.
I think the term affordable still qualifies with ZenFone 6.
For India it'll be starting from 33 to 35K for the base Zenfone 6 variant, as per my speculation.
