i don't think that its going to attract more 10 year olds in the sense of gaming because honestly any kids i know that have a 360 sware by halo and cod 4, so what would they play on the PS3?
I highly doubt i'll see a 10 year old on Socom, or Killzone 2 (well maybe but still its hard to imagine)
It's like Rainbow Six Vegas i didn't ever really hear anyone under 15 playing that game cause it was just too hard.
I think the sales spikes will contribute to the Blu ray player alot also, i mean go get a good blu ray is gonna cost you $250 dollars, go get a PS3 that does so much more than a stand alone player is only $300, so i mean that's also a selling factor, i see the ps3 as a more "mature console" cause the exclusives seem like there gritter and harder than the 360 exclusives.
Example Gears of war was easy for many people both online and off, so is call of duty and halo.
games like Socom with realistic approaches and stuff don't attract the lil ones cause they are all about run and gun spray and pray.
i dunno maybe there will be more 10 year olds playing single player games like Ratchet and Clank and Little big planet, maybe even play them online but some of the gems like MGS4 and Killzone 2,Socom won't see the same crowd.
and TBH, MAG is going to be an awesome game but it is hard as hell, and there is a lot going on, being rambo never works in that game and i love it.
