oni-link on 25 October 2010
I'm still going by VGC numbers as that link you gave just doesn't have much credibility (though VGC can be shoddy at times but hey why are we here?). Still OTHER M SOLD QUITE WELL 510K in 7 weeks is still really good (metroid or not). I'm still waiting for the link to show Nintendo expected Other M to sell 3M units when the last two Metroid games averaged only 1.35 between them and combined for only 2.7M copies!!! 
My predictions:
600K by Christmas
700K-800K within a year
950K-1M lifetime
