The much-hyped Tourney mode will be landing on the Wii U, along with YouTube replay uploads. Tourneys are divided into two categories: Community Tourneys which let players complete for the highest points in a certain amount of time, and Regular Tourneys which have more detailed rules and only happen at certain times.
YouTube uploads will of course require a Google account. We're actually getting this feature ahead of schedule - it was previously stated that it would come after the tourney mode.
On 3DS, new stages and Mii Fighter costumes will be made available. These are paid-for DLC, unlike the elements of the Wii U update.
Will this renew your interest in the game, or are you still playing it anyway? Let us know by posting a comment.
