@NJ5: Yakuza wasn't really spot on. When you compare 156k and 178k it seems alright but it was already known that Yakuza sold 113k on its first day. So in fact Source estimated only Friday-Sunday sales and gave them 43k when in fact it was 65k.
There are actually lots of titles that are terrible estimated in preview (WiiFit, Gundam Musou Special, Monster Hunter Portable 2, Doraemon, Soma Bringer, Harvest Moon plus some titles that can't be compared becouse they aren't in Famitsu top at all). If I made as bad predictions in Prediction League as are in the Japanese Preview I would be losing tons of money.
