Update: According to developer Yacht Club Games, while a physical release of Shovel Knight would be great, and is something the studio is “still looking into,” the Best Buy listings “are just a mis-listing at this time.”
Original: Shovel Knight is getting a physical release across PlayStation 4, Xbox One, and 3DS, according to Best Buy.
The physical version is listed for a September 15 release at an MSRP of $29.99. In comparison, the digital version costs $15. It is unknown if the physical version will come with any additional benefits.
Thanks, r/PS4.
