I have cleared my mind for a day on the subject of Viva Pinata, and I think it might actually be a good idea.
On the one hand, I believe Microsoft is being very naive if they don't consider Wii to be part of the competition. On the other hand, it's too late now to really compete with Wii on Wii terms...360 is never going to be a serious competitor to Wii, so instead why not try to harness it as an advertising tool? In the short run it might dissuade a few old-time Rare fans like myself from buying a 360, but in the long run it could really expand Viva Pinata's brand awareness. How many times have we argued that this game would sell way better on Wii?
Which brings up one more point - it could be a real goldmine for MS Game Studios. How's that profitability coming, guys?
