Why isn't 'Batgirl' a valid career choice?

I know I already posted about DJ Hero earlier today, but there's more news in the world of Guitar Hero: World Tour.  It seems that, in order to keep up with the Joneses...or more appropriately, competing company Harmonix and their hit Rock Band series...Guitar Hero won't just be about guitars anymore.

Like Rock Band, World Tour will come with a drum kit and microphone and will also feature a redesigned guitar.  Unlike Rock Band's four pad drum set, World Tour will feature three pads and two symbols in order to make it feel more realistic.  They'll also have increased sensitivity, so the harder you hit, the louder the sound.  And the redesigned guitars?

The new guitars are especially impressive: there’s a touch-sensitive patch on the neck that allows for sliding solos and more realistic hammer-ons, which allows players to look more and more like Eddie Van Halen (but hopefully with better dental work).

Along with all the new features comes a song list featuring 30 Seconds To Mars, Lacuna Coil, Tokio Hotel, Nirvana, Sex Pistols, blink-182, Linkin Park and more.  But no Green Day.  Sad for some, not so much for the rest of us.  The full track list is available here.

Keep in mind, Rock Band 2's still looking pretty bad ass, with a bigger track list featuring names such as AFI, Bikini Kill, the Offspring, The Who and Panic at the Disco.  Plus, with their constant offering of downloadable tracks, the song library could hit 500 or more by the end of the year.

So, what do you think?  Where do your loyalties lie, Buzznet?
