I can't imagine why so many people are falling into discussing that rumor. It seems to me that there's a million reasons why a GNR Guitar Hero game would be extremely hard to do at this point.

I like what that guy from anti-music had to say on the matter. Universal is concerned about making their money back due to how pathetic sales in the music industry are right now. I say that they should provide a lossless version of it for download through a pre-order on the official GN'R website. Sell it for $10. Don't officially release the album on physical CD, Amazon mp3, iTunes, etc. until you've sold 2 million copies through the pre-order. People are allowed to pre-order as many copies as they wish. There are probably some die-hards out there who would pay $100+ if it meant helping the album get released as soon as possible. In fact, some might even spend as much as $1000 on it. 2 million copies x $10 = $20 million before the actual release of the album.

Even if demand is much smaller than it once was, you could still sell the pre-order for $5 and that's still $10 million before an official release. The pre-order idea is a great way to capitalize on the die-hards' desire to get the album without sending the album to the pressing plant where it will surely leak. The best way to prevent piracy causing a huge dent in the album's sales is to build in a guaranteed revenue from it. A pre-order like this is the best way to accomplish it.
