It seems this title is coming out today in North America, as a trailer has been posted on YouTube:
While ambassadors of the 3DS have had their hands on Mario Kart: Super Circuit since 2011, the rest of the Nintendo community has been wondering when the Game Boy Advance title would receive a wider release on modern devices.
The ESRB has now revealed Super Circuit is making a return in the near future, with the game highly likely to receive a digital release as a Wii U Virtual Console title.
Mario Kart: Super Circuit was developed by Intelligent Systems and was originally released for the Game Boy Advance in 2001. Outside of being the first ever Mario Kart game for a Nintendo handheld, one of the main selling points was the ability to unlock all of the tracks from the original Super Nintendo entry in the series, Super Mario Kart. In 2011, the GBA-hit was then re-released exclusively as part of the 3DS ambassador program.
To those of you in the US, keep an eye for a local release date soon, and to those of you outside of this region, be on the lookout for the usual classification updates indicating a launch date is not far off.
