Great work jonop, I'm back from my holiday so I can update again from today!

Comgnet 2/21

Yakuza 4- 319(+12)

MGS:PW- 121 (+2)

Battle Coliseum Wii- 27 (+3)

They didn't for Samurai Warriors 3 (not known, but evidently well over 250k) or Gundam Musou (1m PS3 only, lol).

not that gundam musou would ever sell a million, but there wasn't even 1m ps3's at the time.

I expect a first week of 444,444 for Yakuza 4.
3rd one did ~350k first week and I see Yakuza 4 doing better on a higher install base and positive reception of Yakuza 3 in Japan.
