Nintendo says it's unaware of Mario Kart Wii problems

Even from the mysterious Joystiq oil tanker somewhere in the Atlantic Ocean, we could hear fanboy hearts preemptively breaking at reports of disc problems with Mario Kart Wii. (Seriously, it was loud. We had to turn the volume all the way up on our Tony Robbins' motivational cassettes just to drown it out.) Perhaps hearing the cries as well from Nintendo HQ (a hovering, edible castle constructed entirely from dreams), Big N is trying to pre-preemptively fix hearts, saying that it has had no reports of problems at all.

Also, Nintendo says that rather than the dual-layer discs that caused problems for Smash Bros. Brawl, MKW comes on a single-layer disc, which isn't really that surprising, considering the same game originally shipped on a Super NES cartridge. ... Wow, we are so going to regret that.
