But why do we ask for "next year"? We await the geula every single day - why push it off another whole year? Moshiach will arrive with miracles that will exceed even those of the exodus from Egypt. The purpose of the world's creation will be revealed, and accordingly, a new system for counting the years will be instituted - the years since the geula. That is what we mean when we say "next year". Let Moshiach arrive immediately and allow us the privilege to begin counting the years anew.
