Will Gran Turismo 5 outsell Halo 3 (lifetime sales)?

[Imaginedvl]

Lol at the results, very objectives :)

With GT6 coming out; I do not see this possible.
The big difference between Halo 3 and GT5 is that when a new version comes out it is still relevant to buy Halo 3 for the story for instance; it is not really the case for GT5 imo
