The Ice Climbers were removed from the upcoming Super Smash Bros. after the development team was unable to get the duo to run properly on 3DS, lead developer Masahiro Sakurai wrote in a column for Famitsu (spotted by Nintendoeverything). According to Sakurai, the team had the Ice Climbers running on the Wii U version of the game, but were unable to find the same success on the 3DS, due to the handheld's hardware limitations.
