I found these results to be quite interesting:
"ERTweekly reports that the survey found 42% of 25 to 34-year-olds would like a games console for Christmas, compared to just 30% of 16 to 24-year-olds."

Personally I think it would be best for Sony to dedicate their resources on creating the ultimate FPS games like Killzone 2 and Resistance 2, instead of adding more too many lower profile games. I think older FPS games are usually forgotten more quickly as the gamestyle is so similar and graphics play a very large role in this gerne (as I owned Unreal Tournament on the PC already, I wasn't interested in getting Quake 4).
As the PS3 is designed to play a central role within the home (the Wii or XBox 360 are more likely to be found in a kid's room instead of under the big HDTV sceen in the living room, the PS3 being a Blu-Ray player and more expensive), I think it's important to please everyone within the family and this will help the PS3 for the long run.
