Bioshock 2 did very well. I did not expect it to sell more than Mass Effect in its first week.
Very bad third week for Mass Effect 2.

That dutch top is still a mystery.

How much ME2 did in its first week in UK? around 70k.?

Just Dance beat the PS3 version of Biochosk 2, that's somethin'.

You have to remember it was an timed exclusive on 360 (original Bioshock) and not many people bought it on PS3 compared to 360. Not that suprising

According to ioi, Mass Effect 2 sold ~110k on Xbox 360 alone.

Looks like Bayonetta also had a price collapse.

MAG got hammered pretty badly, already below Forza 3 and just above Uncharted 2.

Latest head count in the top 40:

X360 --> 13 titles
Wii --> 11 titles
PS3 --> 10 titles
DS --> 3 titles
PC --> 3 titles
PS2 --> dead
PSP --> dead

EDIT: Star Ocean The Last Hope debuts at #11 on PS3 charts, below Avatar. That's a bomba.

About 40% in price drop.
