80 million people didn't defect, more like 55-60 million by the end of the generation. Remember Microsoft only had a 25 million base, but everything revolved around Halo which at the most sold what 8 million? Everything else was mostly third party. Sonys sales have always been spread out amongst various genres. If you asked the majority of their fanbase what they played opposed to Microsoft, you would get many answers unlike Microsoft who markets to a crowd that is a sure thing to attain. Microsoft focuses hard on who shells out the most money and only lays their attention upon them. With Sony it never mattered, which is why their diverse audience would be the most confusing of all the companies to crack outside of GT5 and the annualized games. PS4 will have greater brand loyalty thanks to Sonys showing with the PS3 exclusives, creating more IP's than Nintendo and Microsoft. The Wii U will sell the least and if Microsoft sells even at parity with Sony in America Sony will reach one hundred million consoles by the end of the generation. This generation the market will shrink, because the Wii U hasn't amassed the casuals....remember that. Microsoft is betting greatly on the Kinect 2. Twas a smarter decision to force it upon you than to give you the freedom to choose like Sony has been doing for two generations previously.
