Konami’s working on Rock Revolution in a battle of the band… games, against Rock Band and the Guitar Hero franchise. Activision, now, may be attacking Konami’s current dancing title Dance Dance Revolution with a new dancing franchise known as Dance Hero.
The US Patent and Trademark Office now has on file, an application by Activision to trademark “Dance Hero.” This news doesn’t solidify any real title but tell us their design teams are kicking around some new ideas to attack their competitors turf.
In January 2007, Activision trademarked “Guitar Villain” and “Drum Villain”, with no sign of a game bearing either handle having yet surfaced. This past February, it locked down rights to the title “DJ Hero” without announcing a new product, although rumors of a turntable-based mash-up game bearing the name are beginning to bubble up.

Does another dancing game sound interesting?
As if the week of rumors hasn’t ended, Slash all but confirmed Hendrix as one of Activision Blizzard’s next big hit Guitar Hero games in Rolling Stone Magazine says 
It’s clear publishers like Electronic Arts hate to take risks on video games. They’re not alone in their opinion, look how many sequels we’ve got for the holidays compared to new creative titles like Little Big Planet, or how publishers push out sequels to hot titles until we can’t take it anymore; how many Guitar Hero titles will arrive before we scream “enough!”?
