Super Mario Galaxy 2 sales will definitely surpass Super Mario Galaxy 1's sales by at least 10,000,000. That makes it SMG2 worldwide sales about 20,000,000 units, possibly more.

haven't you done this thread already?
aligned 1.5-2
unaligned 750k-1mil

yeah, didnt we do this one already :P

id say 750 - Mil in US alone.

Worldwide. probably 2-2.25 million. 3D mario games never do as well as 2D (although sunshine selling 5 million, sales figures any other brand would be proud of)
. although this is a first for nintendo, being a sequel on the same console as the original so it certainly will be interesting.

Sunday can't get here soon enough.

I hope that no one that select more than 1.000.000 in it's first week in Americas is talking serious. It might even barely do that WW.

SMG2 will Dominate the sales charts with millions in week one. Wait and see.

Ok then, when I discover that the one I'm talking with is just joking, I leave the thread, so bye.

In US maybe 850.000, with all america included 950.000, very near 1 million.

That's possible in Japan, but not US. 

It'll sell much more in US. Mainly because it has a lot more 2D gameplay, which is what most gamers enjoy.
