Killzone 3 was more undertracked because NPD does't track units sold with hardware bundles while VGC does. |
actually it doesn't look like it.
The Source wrote PS3 sold 328k this month, which is 87% of the Americas sales
He also wrote Killzone 3 sold 205k, which is only 81% of the Americas sales (87% would be 221k)
so unless he uses a different percentage specifically for PS3 games (which I didn't check and I doubt since he uses the same one for the PS3 consoles) he either made a mistake or took off 16k that were sold as bundles, thus making it undertracked by 75k.
And 87% is the usual marketshare of the US in the Americas.
