ModNation Racers (Sony), Split/Second (Disney), and Blur (Activision) failed to light up U.S. sales charts. ModNation Racers, a PlayStation 3 exclusive, was the only new racing title to crack the top 15, while debuts from Blur and Split/Second - both multiplatform titles - were out of the top 30.

That'll teach them to not make fun of Mario Kart, which no doubt outsold both titles this month
Sad stuff. I would've expected MK Wii, but even modnation which had significantly less exposure. Poor debut.
