So I've thinking about sales and what could happen the next couple of years regarding PS3 and the xbox 360. Maybe it's just an open door but I think, in contrast with the 360, the PS3 have some system sellers left that are sequels of popular PS1/2 games which can account for big sales.

• Final Fantasy XIII and & FFIV: in Japan these games should have a massive impact. Probably good for about 1 million of people going to get the PS3 for these games.
• Gran Turismo 5. Need I say more? A couple of million people waiting to for this game to buy the system
• God of War III. Maybe not as massive as the games above, but it still should attract 500K.
• The Last Guardian. Even smaller than God of War, but it's probably gonna be a unique game that'll attract fans of the former ICO games.

All in all these should get at least 4 million new gamers to the Playstation 3. And with the recent numbers of PS3 continuously selling more than the xbox 360 I think the Playstation could end up second in line behind the Wii. 

No this gen will end how it is right now
1. Wii
2. 360
3. Ps3

@Aion

How do you know? You live in 2012?

If PS3 is able to close the gap to 5-6 millions this year there's a shot, but this means next year ps3 need to sell every week an average 100k more...it's a lot even counting megatons, bundles and holidays.

Yeah I guess that's a lot,  but I think the PS3 will be selling more than the 360 every week from now on. Even though both the 360 and the PS3 and the 360 had pricecuts hell of a lot more people bought the PS3.

after 2011 christmas it should.
unless microsoft start giving 360 for free-

lets see how NATAL develops first :)

I was going to reply to the original post, but I just can't find any better response than this^.  

You can't compare the sales effect of dropping the high-end to dropping the low-end.  Dropping the low-end taps into the entire market of those who can't/won't spend over a certain amount.  Dropping the high-end taps into those looking to get more gear for less.  Big difference, that.

There are far too many unknowns to say 'likely'

a few points to consider..

• PS Motion Wand launching early 2010 - SCEA expecting sales of around 5 Million
• Natal launching late 2010 - Microsoft treating it as a console re-launch
• Microsoft likely to cut the price of the XBOX 360 late next year, probably along with the launch of Natal
• Both Sony and Microsoft have a comparable software line up, Microsoft releasing yet another Halo, Sony with GT5 as the big title
• PS3 will still be more expensive than the 360 all year
• Blu-Ray will be mainstream and 3D Blu-Ray movies and games will begin to be released.
• Sony will have the momentum going into 2010

I think Sony will be able to get within 4 - 5 million by years end 2010 but it will depend on Natal.. If Natal bombs then Sony could get closer than 4 million but if Natal is a hit then the 360 will extend the lead back past 5 million.
