According to http://news.vgchartz.com/news.php?id=6112 Wii during the week including NSMBW should have eaten from a minimum of 53000 to a maximum of 87000 of PS3 lead in their respective achievements. Thanks to Mario it will be a closer and more interesting race, we'll have to wait for FFXIII to see if PS3 can build again a consistent lead or if Wii will win... But a tie is not unlikely.
