I do not suppose there will be a season 3. Season 2 has adapted a lot of contents and I doubt there will be any left for SS3.

I do think we can hope for a movie or OVA tho

I beg to differ there's still the Quintuplets Flashback Arc, Summer Vacation Arc, School Festival Arc, Finale Arc & last but not least the Wedding Ceremony to cover. that's enough content for a season 3...maybe even a 4th season but a movie does sound good.
