Xbox 360 vs. Playstation 3 vs. Revolution!

I am always curious as to why and what people have to say about the new next gen systems comming out! I also like to here what people have to say here about who will come out on top and why. Also who do you think has the best marketing plan thus far!? So if you have two cents to give please pay up Because I really would like to open up disscussion on this!
