So the 360 recently broke many milestones from 50m to outselling SNES.But where will it rank when its all set and done

On the other hand SONY continues to grind sales out of the PSP in its 7th year which recently broke 65m mark

360's plus points :

still selling good

good software support

mid-cycle refreshment as kinect

pricecuts

360's negatives :

successor coming on in 1-2 years time

low first party to support 2 consoles

MS would have a stiff competition next generation so they might shift resources away

PSP's plus points :

software support still there

sony is known to keep playstation products selling for long time

Possible alot future SONY phones integrating PSP to keep PSP going for 10 year life-cycle,first PSPhone releasing soon

strong SONY first party to keep it going

pricecuts

PSP's negatives :

bad software sales as a result software support dropping

succesor coming 1-2 years time

So give your predictions and also tell us what you think will be the lifetime of both of them?

my prediction is PSP

lifetime:

360 = 80m

PSP = 90m

I'm thought PSP might pull off a Xbox cut it off and run kind of end, but maybe not.

I think 360 might sell more. PSP is going to have a successor this year.

lifetime numbers?

^^u too

I'm confused, how do these negatives not apply to the psp as well?  Especially since the Xbox successor is nothing but speculative, but we know that a psp2 is going to be revealed at sometime this year?  And psp2 won't have stiff competition from the 3ds?  So Sony wouldn't need to shift resources?  

Also, don't really need a first party to keep supporting an old console.  Sony has barely supported the ps2 at all since the ps3 came out.  Ps2 had some big first party games the first year the ps3 was out, after that all the ps2 got from sony themselves was crappy psp ports.  I don't know if I would really call that support.  Third parties are the primary supporters of older systems after new ones come out.  

PSP 72 million if the new PSP comes out this year

if beginning next year 75 million (I'm probably being generous, PSP is completely dead outside of MEAA and Japan, which will both fall quickly, MEAA being more so)

The way things are going, I can't see PSP winning out -- it'd be lucky to top 75m imo and 360 will more likely than not end up at 82m or so. PS3 vs PSP would be an interesting comparison though.

check again,it was an edit mistake.i have included the succesor for psp's negatives too

PSP2 would have a stiff competition but as you see PSP's positives,SONY has tremendous first party support and they have been known to support platform way after they peak.SONY would shift resources but they have enough in the bag to continue to support PSP as you can see with the PS2.

and if you think SONY hasn't supported PS2 since PS3 came out then please go check again,GOW2 came on PS2 after PS3's release.MOTORSTORM,MLB,SINGSTAR,etc came out too.yeah it wasn't like the PS2's peakdays but it was still supported and ports or not,atleast people were buying it.

"Third parties are the primary supporters of older systems after new ones come out."

you seem to talk in general then go check how third party or first party suppported older consoles like XBOX,GAMECUBE,GAMEBOY when their succesor came out.they didn't support them so much

and please leave lifetime numbers

here, let me highlight the part you didn't seem to read.  Also, you should check how many 1st party games that have come out for the ps2 in the last couple years that haven't been ported from the psp and then get back to me.  (you see, psp isn't going to get easy ports from the ps3, so it isn't going to be the same, the ps3 might get ports from psp2 though.)

Fixed  :)
