[UPDATE on April 15th, 2015]
Developer Yacht Club Games has refuted the listing, saying that while it would be great to make it possible, they’re “still looking into” it, and that the Best Buy listings “are just a mis-listing at this time.”
We’ve learned (via r/PS4) that Shovel Knight is getting a physical release.
While this is unconfirmed for now, a release date of September 15th was also on the listing, for $29.99. The digital version has cost $15.
We’ll keep you guys posted.
