Have Sony found a Halo killer?

[bullsize]

why is Halo 3 such a big game,I know 9.63 mill is a big no. but hey 13 million is a bigger no.
and the game is Call of Duty 4,with 7.5 mill+ units on X360 while the much underrated Call of duty: WaW has sold 5.5 mill+ units on X360 and 10 mill+ units overall.If they were X360 xclusive they wud have outdone Halo 3 easily.Some prefer ps3 to X360 for better graphics so sales are divided.And Halo 3 is not the best shooter ever,its nowhere near to half-life 2 or COD 4.Its just a marketing hoopla that sells it.Its a average shooter with loads of marketing behind it.One word Overhyped,linear,predictable too short.

Modern Warfare 2 will certainly outsell Halo 3.

and games can't be killed.
