I have seen the commercials for GTAIV in the US and there is no mention of the DLC for the 360.  My question is, Why doesn't MS advertise the DLC exclusive on the 360?

They will.  But I reckon most of those ads will be in-store.

yep, just saw 1 during late night on conan obrien. says 'preorder gta4 special edition' at gamestop. very funny about liberty city. think it had 360 cover but gotta watch it again on utube

 The commercial had the art from the box but not the top of the box that says either 360/PS3.  At the end both companies are featured.

Microsoft isn't the one making the commercials, Rockstar is, and I really don't expect them to mention DLC for the 360 in their commercials.

I'm expecting M$'s onslaught of GTAlV commercials soon. I also expect them to twist the truth somehow. Maybe with like an "Only on Xbox" at the end of the commercial, without mentioning DLC. So casuals believe the game is an exclusive.

I saw lots of GTA4 ads today during Ultimate Fight Night and The Ultimate Fighter.

I really dont think the extra content will get many people, isn't it just some new missions? I have yet to fully complete any GTA game, I'm more interested in the rampages and cruising the city, and to my knowledge, it's the same on both consoles.

No one knows what the exclusive content is, but Rockstar has said it will be quite significant.

For the sheer amount MS paid for it it has to be significant.

Either way MS would be crazy to not advertise this.

What a great time it would be for MS to announce a price cut / gta4 bundle in NA.
