Ok I'll look for the link but if you think back you will remember the DLC was supposed to release last year Christmas or early this year. So why would they just now start working on it.

i don’t know how reliable this source is but it gives an idea, and i don’t think DLC will be an island or anything like that

360 GTA IV + GTA IV DLC > PS3 GTA IV

Game. Set. Match.

There is nothing to say anything different. Microsoft didn't spend $50M for no reason.

If it is new cities, I wonder if there will also be additional multiplayer maps. That would also make people buy it...

I have no doubt that the $50 million will be worth it at some point, and the only reason we don't hear about it sooner is the clause in the agreement that MS can't blow the PS launch for Rockstar.

That's my guess.

Hasn't Staten Island been left out of GTA4? I could see it being one of the episodes.  I'd pay $20 for it, if it added 15-20 hours of additional gameplay.

The only real argument I see against this is that Microsoft should have done a bigger deal about it if it's true.

But that's not definitive enough, maybe they can't say so as part of some agreement with Take 2.

 It detracts from the original game because once I had VC I no longer played VC and once I had SA I no longer played VC. Therfore sales of GTA3 declinedas the more recent version came out.

In the same vein, adding what amounts to 2 complete games to only one console as DLC will cause far less people to buy the PS3 version of the game. This will alienate (current polls show 40%) much of R*'s GTA fanbase unless they also put the same content on both consoles. 

Devs are already stated it would be as big as a full game
and CVG are proXbox360

and I assume all is said.

If the DLC is as big as another city with some more missions, cars, etc. I think MS is blowing it since they are not advertising it. I still know many people, myself included, that do not have a PS3 or 360 and this game is a console seller. Because I have yet to buy a console I don't see the DLC being something as large as a new city or they would try to get my (soon to be console buyer) attention.

The lack of details about the DLC leads me to believe its not as big as a new city. I think it will probably be more side missions and more multiplayer modes/options. However the side missions and multiplayer modes would have to be pretty impressive to justify the price tag.

If the DLC is as big as a new city MS better get the word out soon or they will lose a lot of console sales. I'm leaning towards the PS3 for the blu-ray (which I can rent), free online play and more dependable system. I love GTA and something like a new city would then make my decision more difficult.

Wrong

both games had completely different stories, people, cars, building etc. this  DLC will NOT have this. a new area like an expanstion thats it.
