The multi-platform games have also been worse on PS3 than XBox.
Basically, I can see 3 potential "big" audiences that the PS3 is missing out on:
1) The hardcore gamer: Not standing for Sonys lying and knowing that the games so far have been better on the 360.
2) Casual: Wii has taken most of them, but then Madden is better on the 360 as well so if they were looking at a PS3, they're not right now.
3) Kids: Just too expensive for your average parent.
I definatly see the PS3 finishing last in this generation but still do alright, just like the Gamecube did. The only problem for that scenario is that Sony is bleeding money on this thing hoping that game sales and Blu-Ray sales make up for it. If you look at sales figures for the last games in the franchises of FF and MGS, neither of them will save it, the people who make up the most numbers in console and games sales now are the shooting/sports loving guys, just watch the sales charts after Christmas.
As much as I wished they would, FF and MGS are not console sellers anymore
