Sony got comfortable following Sega . Sega Saturn launch is closely followed by PS1. Dreamcast launch is followed by PS2 launch. Sega only sold about 10 million of each, Sony sold many tens of millions.
Then Microsoft made things harder. Xbox360 launched first. But this time the console before it, the Xbox had sold pretty successfully for a new entrant (24 million +, slightly more than the Gamecube apparently). And Microsoft weren't about to do a Sega by only managing to sell 24 million Xbox360s. They got very 'user friendly'. Their games and presentation became a bit.. cuddlier and more professional, less needing to shout about raw power now that they'd got noticed. But it was also a taste of the future to be able to play HD games for the first time. With Rare now releasing more games and the Wii not impressing some long term gamers, the Xbox360 probably attracted a fair few Gamecube players. The Kinect will have also helped to cement that the Xbox360 had something for you if you were traditionally a Nintendo kind of player.
Sony can't allow such a long gap between the 2 consoles being launched this time. The Move, a fine concept in its own right, had a sense of desperation at the time which it could have avoided if it had launched it first as they had already used part of its set up, the motion control camera, with the PS2.
And Sony won't get by just relying on shallow 'cinematic' types of games to start with. People really started to buy the PS3 when it had a good mix of arty and fun games.
