The hardware is generally equal in terms of power, but the PS3 has a slight advantage.
If you honestly think there is going to a major difference in graphics between the PS3 and 360, you are mistaken, at least right now. Maybe in 2 or 3 years when devs have had enough time to play and learn each system you'll start to see big difference.
that video was too awful to make any kind of comment on it, to be honest having a high end pc kinda negates the idea of having any console. Because either now or by the end of this year, PC's will be beyond the graphical scope of the next gen consoles.
i think the reason people who were not planning to get an xbox, have, because the ps3 will be so damn late. they probably thought what the heck, i want a next gen console now, so the buy the 360. whereas i couldnt care less, ill wait, and wait, and wait, until my ps3 arrives on my doorstep. or i could go and pick it up from a shop lol.
