not really... until now it only proves that it got there faster... the last weeks numbers aren't so bright... i am afraid that only U1 fans are buying U2... hope my opinion change in the near future!

How so, if Uncharted 2 was a system seller?

Why were people talking about Uncharted 2 being a system seller?  Maybe it had a marginal bump for the PS3 when it came out (around the same time as the Slim/Price cut), but people were making it out to be some sort of thing that pushes more PS3s.  I didn't get this at all, and I am fan of the Uncharted series.
