With both games potentially coming this fall, which one do you think will sell more first week, and Lifetime?

I predict.

Halo 3 ODST sells better first week.
GT5 sells better lifetime

I think this is a pretty obvious outcome...

halo will because it has a huge fan following and its a shooter.
GT5 has a very large fan following and is not a shooter

If it were full Halo 4 then maybe we could discuss it.

Becouse it's more of short spinoff I think it will have sales slightly better than gt5 prologue.

i dont know i was unawear until recently that gt has a huge fan following. but gt is also on the ps3 so that may hurt in the end

Comparing 2 completely different genres. It will be GT5, but Halo:ODST will be played online a lot more online.

Id like to think so

Halo: ODST and then Halo: Reach will own both of them.

You think ODST will sell over 7m lifetime? Cause GT5 will.

And what about 1st week, which is more interesting
