This. Really, I can't recall the last time MS paying for advertising actually helped them sell more copies than the PS4. Or really boost HW sales all that much either.
People need to stop thinking this is all about Xbox trying to outsell PS. Its about Xbox trying to sell more consoles and games. PS4 doesnt need marketing to outsell the X1, the generation has already spoken. PS4 will outsell the X1 even with anti consumer practises and censorship etc. They could release mediocre games and still outsell the X1. Its a sad reality.
Xbox need E3 to recreate there brand where as PS doesnt. Having marketing rights wont affect Sony but it will help Xbox.
