ZOMGH @ demon's Souls overtracking!

Niche and casual games are very hard to track.

I'd say ouch for Demon's Souls, but it's done 3x what they expected.

Atlus is doing damn fine, and I feel great with that.

Dude 3.73 times actually  

That's too much difference. Those games need a correction.

Agreed, though VGC usually seems pretty good on the casual end.  Megamix is likely severely undertracked, as I seriously doubt it's overshipped.

I can't even find the number 280 in any context in that presentation, so which part exactly is saying which games sold how much and their expectations?

I'm not too surprised, that Demon's Souls is overtracked, but ~300k really is a lot more than I expected.

Not trying to start a flamewar here, but I could imagine that another well known JRPG is probably just as much overtracked as well...
