Nah, I doubt sony will resort to charts and comparisons, they give you what you get upfront, then let the games do a lot of the talking.
Apart from the initial boast the give with their hardware at E3, they usually don't do a whole lot of that, they don't have to worry about it like MS does.
Notice how this report was only generated after Sony took all of the Buzz at E3...had it been different we'd never see this. It's called dirty play.
