Wow, this has got to be the biggest PR messup whatsoever. You can say whatever good things about your own products, whatever bad things about your competitors, even distort the facts, but pointing out that your direct competitor's product is good? (Well, I really don't believe they believe Wii and PS3 aren't competing...)
Unless the writer took his quote out of context or even misquoted.
"Well, the Xbox 2 sucks. Look, even the Wii is more fun than the Xbox 2, but the PS3 is even more fun!"
