With my 80gig Motorstorm bundle I had the sixaxis controller, and soon purchased another.  I was quite happy with my 2 controllers and despite wishing I had Dualshock 3 instead I had decided to not upgrade.  The day after I got LBP I ended up going to buy 2 new controllers so that three of my friends could join in.

After selling 2.9 million copies, what do you think is a reasonable estimate for Dualshock 3 sales which otherwise might not have happened as people like me wanted the full local coop experience?

Also, do you think that VGCharts should track peripherals to see what boosts might be given to such with game releases...

Good question....I bought 2 my self

Killzone helped sell 1 Dualshock 3....

i got 3 ds3 after getting LBP

LBP helped justify a 3rd controler for me for sure =p but KZ2 was the main reason, i only had 2 sixaxises

I got one sixaxis because the release of LBP was near, and once i got it i got my first dualshock at xmas lol

Circuit city going out of buisness sale i got it 50% off... that was my reason

I bought 1 DS3 after I got LBP. I think it helped Sony quite nicely.

^^ I agree with Killzone 2 also being a prime motivator for Dualshock 2 Dualshock 3 sales.

Fixed

i got my after msg4.
