I think it's safe to assume Zoro will have a role being that he's a supernova and has ties to Kadio, but how much of a role depends on how much of a Luffy show Oda wants it to be among other things. That takes not just reading comprehension which is reading the lines, it takes understanding the kind of story the writer is writing. All that to say, better to keep your expectations low and have them be surpassed than the reverse.

Basically- Luffy is still going to be number one, no matter what,
