Why Wii doesnt get the coolest games?

Im a Wii owner and im screwed because of that, we all know that stuff like zelda and mario don�t hold a candle for stuff like Saints Row and Dirt 3, THEN WHY THE HELL ISNT THAT STUFF RELEASED ON WII! i ask you people, should i give up and get a XBOX, or should i wait for WII U to be released in hope for better games from PS3 and XBOX?
