We ran out of letters...., after Generation X, Generation Y, and the current generation, Generation Z, how are we going to name the next Generation?

The Z being the last letter from the Roman/Latin alphabet, we seem to have a problem….
How will we call the next Generation?
Generation 2.0 ?
Generation 2.1 ?
Generation Zzzz?
What say you?
