It was actually easy to see that this guy was joking, without even bothering to check the original article. At least that's what it seemed to me.
I mean, at the beginning he seems to have a point but it all falls apart when he starts suggesting that Nintendo doesn't know what it's doing based on the style of the recently announced Kirby game. At that point, I got the feeling it was a joke, but I knew for sure it was one when he basically started filling a Wii Bingo board on his later paragraphs.
Nevertheless, the Kirby joke and the comic strip about the E3s this year earlier in the topic made my day hahaha.
