:The first of the two pieces of Xbox 360-exclusive downloadable content for Grand Theft Auto IV will add approximately 15 hours of gameplay to the 360 version when it hits this November, according to an unconfirmed report from web comic RPG-TV.

Allegedly sourcing a Microsoft London representative, writer Chris Thomas further claims that the new Xbox 360 dashboard--packing an updated look, game install support and Netflix streaming--is likewise slated to arrive in November.

Both Microsoft and Rockstar Games have remained mum on the details of the exclusive GTA 4 DLC, only confirming that it will arrive this fall. Likewise, Microsoft has only officially stated that the new Xbox dashboard will hit in the fall.
