Think you know everything there is to know about EA’s upcoming rock rhtyhm title, Rock Band? If your answer is a resounding yes, you should think again, as a new wave of information has hit the rocky shores of the internet. Chatting away with TheBBPS.com, Harmonix’s PR representative recently wiped away the confusion surrounding the bundles to be available on the launch day, shed more light on the post-release DLC, and much more.

First of all, in case you have been planning to pick up only one peripheral when Rock Band ships on November 23rd, you’re out of luck, as Harmonix has confirmed that the game will be available in one and one bundle only. Reason, you might ask? Apparently, making the three peripherals available as standalone products right off the bat would prove too costly and retail stores across North America wouldn’t be exactly happy at the idea of having had to display four different packages at the same time. If $169.99 is simply too much for your wallet to handle, you’ll have to wait until early 2008 for the peripherals to be made available separately. Speaking of the price, here’s what the PR representative thinks of it:

$100 is asking quite a lot for just a guitar and a game, we think asking $70 more for the drums and microphone that change the experience is an amazing value.

Next, Harmonix confirmed that the PS2 version of Rock Band won’t have support for post-release downloadable content nor will it feature online play, as the console, simply put, is just too outdated to handle those features. Also good to know is that the issues that once plagued the PS3 build of the game are now gone:

Early in development the PlayStation 3 version just didn’t look as good [as the X360 version], but we caught it early and now you can’t tell the difference.

Moving on, the Harmonix PR representative wasn’t ready to disclose whether or not the post-release downloadable content will be more affordable than the current infamous DLC for Activision’s Guitar Hero II:

I don’t know if I can say we’re cheaper or more expensive but remember, where as in other games they adjust the tracks for one or two guitars, in Rock Band it’s vocals, drums, guitar and bass on multiple difficulties. One thing we will do is give the gamer options. You can buy an album, or if you only want one or two tracks you can purchase those items separately.

Also worth noting is that Harmonix plans to release The Who’s Who’s Next album as soon as a week after the release of Rock Band, with more content to be made available every week leading up to the end of the year.

As for the number of tracks to be featured in the game, more than 40 but less than 50 songs are to be included on the disc, excluding the unlockable ones. Should you wish to read more about the game, check out the whole thing over here.

Rock Band is coming out in North America on November 23rd for the PS3 and Xbox 360, and December 17th for the PS2. Europeans will sadly have to wait until next year.
