Guitar Hero World Tour Outsells Rock Band 2 TwoToOne

GameSpot Australia got a report from The NPD Group of combined U.S. sales for both Guitar Hero World Tour and Rock Band 2 across all platforms and SKUs and found out that the first full-band (drums, guitar/bass, and vocals) installment in Activision's billion-dollar franchise sold 3.4 million copies domestically, exactly twice as many as Rock Band 2's 1.7 million units. But is the unit sales comparison fair? From the article:

Besides being available in more retail configurations, Guitar Hero World Tour also went on sale on all platforms--the Wii, Xbox 360, PlayStation 2, and PlayStation 3--on October 26. By contrast, Rock Band 2 rolled out onto its console on a staggered schedule, hitting the 360 on September 14, the PS3 October 19, and the Wii and PlayStation 2 on December 18. That means that only 13 days' worth of sales on the two latter platforms--which have the biggest installed bases in the US--were recorded by NPD.
