Let us speak plainly.
Money talks. And when Carnival Games outsells Punchout, The Counduit, House of the dead Overkill, Dead Space: Extraction, No more Heroes, Tales of Symphonia, Okami and Fire Emblem COMBINED what sort of a message do you think that sends to third party developers?
Too bad there's no data on World of Goo though (Wii's only AAA rated third party exclusive).
And despite that, many core games are still on the Wii and many core games are coming to the Wii. I wonder how that must work out for you :(
Yeaaaaaaaaaah....I don't think companies are so close minded that one exception puts them down like you'd like (hope) to believe.
