For those willing to fork over the extra cash, Rock Band 3 will offer "pro-mode" guitar tracks as DLC.
MTV's Paul DeGooyer told IGN, "The only thing that's more difficult for us in terms of authoring time is the guitar stuff, so we've decided to sell Pro Mode for guitar separately. If you're not interested in Pro Mode for guitar, you can still get the DLC that should conform to our current DLC pricing, and you get Pro Mode for all your other instruments."
For those who're considering buying the guitar Pro Tracks, DeGooyer says that players will be looking at about $1.99 per track.
"It's not going to be five bucks or anything. We think it's a really fair price," he said. "The alternative would be of course to include it (in the regular download) and up the price for everybody, which I don't think is really fair."
Also, don't expect to see all your favorite tracks from Rock Band 3 with a Guitar Pro Mode equivalent, as only a select amount will have this option. DeGooyer also stated that there are plans to include pro mode for some songs of the previous Rock Band titles.
"We haven't completely worked out exactly how we would be able to get it to market, in a way that recognises people who have already purchased it, and thus be able to supply the updated file at a discount, which would be our preference," said DeGooyer.
Rock your socks off in Rock Band 3 on October 29th.
