May you have many more in German language?

There are a couple of ways to say "May you have many more" in German, depending on the context:

Formal:

* Mögen Sie noch viele weitere haben! (This is a very formal wish, often used in written communication or speeches.)

Informal:

* Mögest du noch viele weitere haben! (This is a more informal version of the formal phrase.)

* Hab noch viele weitere! (This is a very casual and direct way to say it, typically used among friends.)

* Alles Gute für die Zukunft! (This translates to "All the best for the future!" and is a general well-wish.)

The best choice depends on the situation and your relationship with the person you're talking to.
