Mentioning Wii was probably a goof by the magazine in the first place, a fumble in their strategy. Keep the platform spec ambiguous so that the Mickey news invites "all readers/gamers" instead of shunning PS3/360 from the get-go, getting more people to checkout the magazine. Maybe later they'll spring "exclusive to casuals," but only after they got the attention they wanted.
The exclusivity on info/content only benefits GI way more than Disney.
