Now that I got your attention with the title, let me explain myself.
The 360 and PS3 are both competing for the hardcore gamer market. The Wii has shifted gears and is now targeting just about everybody who lives on planet Earth. Microsoft has a huge agenda, something that I have no idea what it is. But I do know their current agenda goal that they must accomplish: overtake the Playstation brand to control their market share.
*** Microsoft is focusing all its resources to control the hardcore market.*** AFTER, and ONLY after will they focus on directly competing with Nintendo. So, it is commonly known that the 360 is struggling in Japan. ***Now until Microsoft figures out to crack that market, how are they supposed to slow down PS3 sales in that region?***
The answer is Nintendo. In order to prevent as many PS3's being sold in Japan as possible, Microsoft needs an outside source to take away Sony market share. The Wii is the more precise answer to that. With the Wii's amazing sales taking away from the PS3's, this gives Microsoft more time to crack open the hardcore market in Japan.
Hopefully, the Wii can hold off the PS3 long enough for the 360 to get some great exclusive Japanese-style games that will drive sales. Blue Dragon gave sales a boost and games like Lost Odessey will continue that trend until the 360 is more established. Nintendo is very generous for helping Microsoft against Sony free of charge.
