Mario Kart 8 may feature the series' first-ever track editor, according to a new rumor concerning the Wii U game.

The first mention of the new track editor came from the product page for Mario Kart 8 on online retailer Newegg. Nintendo has not confirmed this feature, and no other websites list the feature as appearing in Mario Kart 8, so it is possible that this is a mistake on Newegg's part. However, it is also possible that Nintendo has been keeping this secret under wraps so they could surprise fans closer to the game's May 30 release date. No other game in the series has had a level designer, so the ability to create new racetracks for the game would certainly appeal to fans both old and new.

Nintendo could have several options for how users create different tracks in Mario Kart 8. The most logical way for users to design and edit courses would have players use the Wii U Gamepad to control the feature. Using the second screen on the Gamepad players could work on their track while leaving the television for other tasks.

While it is still a rumor that Mario Kart 8 will get a track editor, Nintendo has revealed several new features that will be included in the game. Customizable karts will return from Mario Kart 7, and it was also revealed that all seven Koopalings will be playable in the game, expanding the roster drastically. Jumping on the video sharing craze, Mario Kart 8 will feature Mario Kart TV, which will allow users to share videos from the game through the Miiverse. Finally, the game will feature a track with anti-gravity features that will allow players to race through the course while upside down.

Mario Kart 8 is set to be released on the Wii U on May 30, and the game is considered by many to be the highlight of Nintendo's spring game lineup. The series has had an impeccable reputation ever since the first Mario Kart game was available on the Super Nintendo. With Mario Kart 8, the first entry in the series for the Wii U, Nintendo hopes to continue to drive interest up for the struggling Wii U, which has not sold well despite being the first next-gen console released.
