you have to take into consideration that WD had a global release day one. while AC usually releases in EU and other countries a few days later. still impressive though.
Would be pretty strange to not align the launches for AC in that case. Actually, the biggest AC yet (ACIII) released in Europe on the same day as USA. That game sold 3m on PS3+360 FW. Crazy
Off-topic: Why the hell did Brotherhood sell less than Revelations? This is a crime. Must be due to that awesome Revelations trailer.
