Rocksmith has garnered 1.4 million sales. In the press release past the break, Ubisoft boasts it has sold 3 million DLC tracks to date and promises "exciting Rocksmith news" at E3 next week.
Rocksmith was met with a mixed reception. Our own review criticized Rocksmith for its lack of music theory education, awkward audio latency issues and dearth of all nuance in the automatic difficulty tuner. An expansion focusing on the bass was introduced back in August of last year.
