After

What changes are waiting for us in the coming year and after? Are we going to make any progress?

What's wrong with "after"? To me, the sentence reads well. I agree that "thereafter", "after that time" or even "afterward" is more formal than "after". However, I am not convinced that "after" is ungrammatical.

"What changes are waiting for us in the coming year and after [that]?"

Or

"What changes are waiting for us in the coming years and after [those coming years]?"

The "coming years" might suggest the rest of a life, however indefinite, and "after" might suggest the Great Beyond.

What do you think?

Thank you.
