GT5 lifetime. First week could go either way.

Halo 3 ODST by at least 3 million lifetime.....

It depends on circumstances.

As things are now, Halo 3 ODST will win week 1, GT5 will win lifetime.

IF the rumoured slim/pricecut for PS3 appear, GT5 will win both.

First week- Halo 3 ODST
Lifetime- Gran Turismo 5 (ODST is a spinoff)

GT5 will win overall.

Wow, a lot of people getting their hopes up of the ps3 slim selling well lol......

And why shouldnt people get there hopes up?

I predict GT5 bundles, more then likely GT5 wins others first week Halo gets americas. Lifetime Halo ~ 4 mil GT5 ~ 5.5 mil.

halo ODST is a spin-off so I think gt5 should sell more first week and lifetime, also halo reach is one year away so it will pretty much cut the legs of ODST in the long run

Good point.
