What are you talking about? The original iPod worked with the Xbox360 because -Microsoft- not Apple, built it to support streaming media content from FAT32 formatted external usb devices... The iPhone/iPod touch doesn't work because it doesn't show up as a FAT32 mounted drive... If the iPod touch market share gets proportionally large enough, -Microsoft- (not Apple) will probably fix it in an Xbox 360 dashboard update.
Zune would work on PS3, Wii, or AppleTV if Sony, Nintendo, or Apple cared to capture the 0.2% of the market that gives a crap about Zune interoperability. But since 100% of those guys own an Xbox360, doesn't look like it'll happen anytime soon...
For the record, I'd put money on Xbox360 supporting iPod Touch before Wii or PS3.
