Why Ice Climbers Aren't in Super Smash Bros. for 3DS

Curious as to why Ice Climbers aren't included in Super Smash Bros. for Nintendo 3DS?

In a feature in Japanese magazine Famitsu, the game's producer Masahiro Sakurai noted how the pair were running in the Wii U version, but due to hardware constraints of the 3DS, weren't included. Ice Climbers just couldn't work in the 3DS game.

He also revealed how Akihiro Toda, writer for the iconic Mother series, wrote the descriptions for the trophies in the game.

Do you think Ice Climbers should be included, at least in the Wii U version?
