Then hopefully we can see them soon.

Regarding the original question - While Osana will certainly be a milestone in the development, in the final game she will be the first and weakest rival, possibly even a tutorial-style rival. Her character will probably be the least unique of all the rivals, so I believe the suitor would also be someone who's not really special in any shape or form. My guess is one of the teachers' pets.
