I think it's interesting to see the aligned launch graph ( http://vgchartz.com/hwcomps.php?cons1=Wii&reg1=All&cons2=PS3&reg2=All&cons3=X360&reg3=All&align=1 )
where the PS3 is almost at exactly the same spot as the xbox360.

I don't think it will increases sales dramatically until it gets to the $350-$425 price range (9-12 months from now?).

As soon as Sony has the balls to drop the price to the 360's, the PS3 will sell more.

@rage4dorder: We are talking about the american numbers in this thread ... you are using the worlwide graph ... if you change the graph to america, than you will see a different picture ...

I would say never but that is just me...

very very soon... ))

With MS pushing so hard in NA, it'll be hard for Sony to catch them on home territory, but it is possible if we look back in time.
NA is hardly as important to Sony as it is to MS though, EU and Japan have always been Sony territory over MS.

If people want to expand beyond the usa I say in europe the 360 will again stay ahead mainly due to the price and software. Not sure if anyone else notice the core 360 cost as much as a wii and will be reintroduced with a 250mb memory card and wireless controller. If anything you will see alot of wii360 around the world obviously except in japan. Basically you can have casual from nintendo and hardcore from ms for the price of a ps3. Again in this gen for me at least it is all about price and software with ps3 having by far the worst of those two.  Regarding Japan I am assuming MS is waiting for the new falcon mobo to drop down the price in Japan to at least half of what the ps3 cost and I mean the premium. 

It won't pass the 360 in monthly sales. July was the best chance for Sony to steal the momentum in the US market this year. From this point on, MS is hitting with a barrage of high quality software across multiple genres. That combined with the 360s price advantage will ensure that the 360 maintains its momentum over the PS3. The only way I can see them doing so is for them to drop the price again on the PS3 in the Spring of 2008 near a major release. Assuming MS doesn't counter with a price cut of their own, the PS3 would have a shot at usurping the 360 in U.S. monthly sales. The problem is that the longer the PS3 is behind, the harder it will be for it to gain any momentum.

I'm going with "never", guys. Sorry.

Obvioulsy, not in 2007,

Possibly in 2008 (during some special momentum big games+price drop)

what people forget about momentum is that PS3 has increased her sales by 2 with her 100$ price without any games.
And after 1 month, the factor "2" is still here...
