It's late and I'm getting old, so I've not read the whole thread. I do own a 360, though, and so feel vaguely entitled to spout off some opinions.
As far as I can make out, and having spent a good deal of time perusing the System Wars forum at Gamespot (actually most of the forums seem to be system wars there, but,,,) the 'More Power' argument generally invoked by PS3 advocates is based on fairly thin logic ice. They'll say something like 'but it's got eight 3.2Ghz processor cores! It doesn't take a genius to see that makes more power!' (actually they'd use more exclamation marks: I'll put them in for authenticity: !!!!!!!!!!!!!!!) But if pressed on the matter, few people can really explain how having eight shit hot processors is any better than having three, as I gather the 360 does. The argument becomes a bit redundant because few people seem all that well versed in the ins and outs of multi-core computer programming. It's not always the case in life that just having a load of stuff is better- stuffing a Bugatti engine into a Mini doesn't automatically give you a car that can travel at 250mph but can also be carried in a suitcase. Probably.
But as a 360 owner I wouldn't say I'm particularly happy either. I resent having spent a good chunk of money on something which, by anyone's reckoning, can be very tempermental. Should I have the nerve to accidentally touch my 360 when it's running then, sure enough, red lights spring up. I have to turn it off, put some Bach on in the background, and wait for it to calm down. The DVD drive often doesn't come out when I press the eject button- it just clunks around pathetically until I pry it open with a pencil. The very fact that the console comes WITH it's own series of flashing red lights as code for just how broken it is makes me suspicious. It's hardly as if it can be claimed that the makers had no inkling of the faults. More than anything the 360 seems to scream 'rushed to market'.
And the Wii. Who knows about the Wii? It's such an unknown quantity at the moment. Part of the fuel for the demand seems to be it's scarcity, the newspapers telling them this is what they want, and the kids wanting it 'cos everyone else seems to have one except them. I like the Wii- Mario, Zelda...um...others, they make a good use of the controller and the console, and everyone has a good time. At the same time I'm not wholly convinced it's not a flash in the pan, that people will realise that motion sensitive controls can (and certainly will) be accomplished on other home consoles, alongside superior graphical fidelity and better online functionality. Nintendo didn't invent motion sensitivity, and if there's not a bit more imagination shown in using the motion sensitivity then there could be trouble. What's the use of mapping jump to a sharp, upward jerk of the Wiimote? It's just replacing one repetitive gesture with another- normally you'd move your thumb and press a button.
Anyway, that's a review of the past and present. If my years of gaming have taught me anything, though, it's that predicting the future is entirely hopeless. I can be fairly confident, though, that the PC will always be there, sitting patiently in the wings like a zombie stagehand. The old girl's got life in her yet...
