In Greece on January 1st they wish:

Khronia pola
(May you live) many (more) years

In my nameless language I'd translate it as

Ma ya ra
(or Ma yara)
A-lot (of) span(s) (of a) rotation/revolution
Many years

I'd also say

Ya ra yau!
Good/Sweet/Happy year!

Yes, that language is still pretty primitive :)

Happy new year to you all!
