Last year when Nintendo announce their new system, nobody knew what the REVOLUTION was gong to offer that had NEVER BEEN OFFERED BEFORE. When nintendo announced their controller it caught everyone off guard (especially Sony who had already begun production on their own PS3 system). At first nobody took it too seriously, least of all Sony who kept working on their own system. Later, as the Revolution started getting more publicity, the controler started becoming more popular. By the time Nintendo changed the name of the Revolution to the Wii, and plans were being made for the E3, suddenly Sony announced a change in its controler, a Wii like system that would allow a few games limited multi-range capablility (but not nearly as good or as flexible as the Wii). Since that time the Sony controler has been considered a joke by most of the major video game review boards. It can't decide if it wants to be a XBox controller or a Wii controller, so instead it's stuck somewhere in the middle.
Now, as for nobody LIKING Nintendo's characters, get real. They are only the most popular, and best selling video game characters on this little place we like to call Earth. If you think Mario is only for kids you need to get out of your house more often. And as for Link, it is selling mostly to young adults (the same one's you said would never want it, sorry, but the numbers don't agree with you)
And please don't even try to compare Sony to Nintendo when it comes to kids games. Sony is basing the majority of it's sales (very expensive sales) to one target - hard core gamers. Nintendo has traditionally been known as the most kid friendly system, and now they are expanding that to reach all levels of fans. The only fan base that will stick with the PS3 are again, the hard core gamers (at least the ones who don't go with XBOX). One of the biggest attractions of the Wii is the ability of any player (even my wife for example who doesn't like to play video games) to pick up the Wii's new controller and very quickly be good at playing whatever game. With the PS3 if you haven't grown up with a video game system, it will not be comfortable enough for the average person get the hang of quick enough to want to keep playing.
Does Sony have better grapics? Again, yes they do (although if I want the best graphics I'll stick to my PC), but as even you can see with this simple little poll, the Wii is going to kick Sony's backside all over the place. Don't mistake Sony's limited quanties for better sales.
