Diminishing sales on the Wii versions. I can't believe Call of Duty 3 is the highest selling on Wii. World at War was decent on Wii but lacked more features than the other versions that followed (when compared to the HD versions). Pretty obvious that there isn't too much of a CoD following on the Wii. I own WaW and BO but I refused to get MW3 after all the glitches and crap that were on BO (Wii). Hell, they never really fixed the host freezing problem (only occurred every so often but still happened to me 20+ times). Decent amount of cheaters too... Basically, you are the beta tester with every CoD release.
