Well I think it is early to tell. Ignore the tech, the numbers, the hype... all of it.
All 3 consoles will play online, that is not a factor in choice.
It comes down to the games and such. Do you HAVE to play GTA as soon as they come out, rather than wait until they come out on PC or Xbox? Do you live for Metal Gear? Then PS3 should be a very real choice for you.
Is Halo your game of choice? Have you been a life long fan of DOA? Do you just like the style of gaming that Xbox offered (imo xbox was more of a gamers console than the ps2)? Then 360 could very well be for you.
As for Revolution, you didn't ask about it, but Nintendos games are far more established so I wont waste time by listing them.
Then there is price. At the moment it looks as if Revolution will be the cheapest, 360 will no doubt be in the middle (after being out for a while by the time the) PS3 comes out for a massive price tag (that you will need to "start saving" for.
Of course you may want your console NOW. In which case, 360 would be for you. What is better, spending 7 months thinking about which console to buy, or spending the next 7 months with a console that is still new, with the possibility of buying another one in a few years?
Controllers, they say the 360 controller is the best conventional controller ever, and I don't doubt that. I say the Rev controller will be for games what the mouse was for computers (well, bigger than that. The PS3 controller is a bit of a joke, they say it is as comfortable as "holding a steering wheel", but who holds a steering wheel with two hands when they drive? No one I know. But Sony wouldn't of made it if it didn't work, so I am sure it will work just as good as the PS2 and PS1 controller.
Forget the specs, put them out of your head, it doesn't matter, they will never matter. They don't process the amount of fun or value you get. The games do that, and all the consoles will play all the games.
