Last week CVG had a story from the Official PlayStation Magazine, a print entity partnered with the website, about limitations Rockstar faces on the 360. For almost the first time, we're now hearing about a title where lack of space on the disc and the lack of a guaranteed hard drive may be detrimental to Microsoft's console. "[Rockstar's creative vice president Dan Houser] continued, 'To be honest with you we haven't solved all those riddles yet.' The difficulties aren't limited to working on Microsoft's box, as Houser explains that 'both have enormous challenges' and that 'both have their own particular pleasures and pains'. Rockstar hasn't said anything about a target SKU between the two consoles, but they're currently demoing the game to press running on an Xbox 360 - so we wouldn't worry too much if you've only got Microsoft's console. Look for more on GTA IV in the next few weeks."
