Hibs claimed their final place after goals from Gary O'Connor and Leigh Griffiths earned them a 2-1 win over Aberdeen on Saturday and were joined on Sunday by rivals Hearts after their last-gasp 2-1 win over Celtic, and Sproule cannot wait for the encounter.
Sproule told the Edinburgh Evening News: "We honestly didn't mind who we got in the final because the biggest thing for us was that we just made it through. But obviously it is now going to be a massive occasion for the whole of Edinburgh now that it is a Hibs vs. Hearts final, you can't deny that.
"It's going to be so special for the city, for the fans, for the players and management teams involved, for absolutely everyone with a connection to either team.
"I don't think there will be anyone left in Edinburgh that day and I think that it will probably be something that the supporters talk about for the next month and enjoy the build-up to it. I'm sure that Hearts will be just as determined as us to get their hands on the trophy so it is going to make for one cracking cup final."
Sproule has scored four goals in 36 appearances in all competitions for Hibs this season.
