Smash Bros. for Wii U has Unused Animations for Custom Moves

Hackers have found what appears to be animation from additional custom moves for Super Smash Bros. for Wii U.

In the games, for Wii U and 3DS, players are able to collect and use custom moves for each of the playable characters. Each has three different specials per direction, amounting to a fair bit of flexibility when it comes down to custom matches.

However, seems as if there may have been four per character, instead. Uncovered on the disc by skilled sleuths were unused animation for these moves.

Would you have liked to see some of these moves implemented in the final game? Would Nintendo include them in the future?
