Talk about a name dropping, E3 is all about hyping upcoming titles to get people stoked and talking about the games. Nintendo had very little to say but to let the name slip Guitar Hero On Tour: Decades with a few minor tidbits about what we can expect.
First, we can expect massive carpel tunnel syndrome. Second, you can expect something similar to what we’ve seen in Guiter Hero On Tour with a few minor tweaks:
“They did reveal that the game will feature song sharing between Nintendo DS handelds, which would mean one copy of the game has the potential to have a song the other doesn’t? Could there be DS downloadable tracks in the near future?” (kotaku)
It seems a bit quick to be pushing towards yet another release, although no dates have been set besides “coming soon.” Had it been Sony, we could expect soon to be a few years, but Nintendo is usually pretty prompt when it comes to release schedules. Of course, they’ll wait for the On Tour sales to die down before we see the Decades release.
Unfortunately no songs have been talked about yet, it was really more of a name dropping than a detailed announcement. Perhaps they didn’t have a large enough E3 press release time slot, or they were much more jazzed to talk about the Wii Motion Plus product and Wii Sports Resort.
Another PSP Coming: 
The same company that brought us the NES Advantage has proven the Wii control scheme isn’t as bad as critics speculated. The beauty of adding the “waggle” technology is limiting your button count to a reasonable level without overwhelming gamers.
Sony took pieces of this concept in their PS3 controller and its ability to detect “tilt.” Xbox 360 stuck with the beefy controller with lots of buttons and analog sticks. Not just a D-Pad but two analog sticks and a ton of buttons to press, some pressure sensitive as well. What of our next-generation console? Maybe a few new buttons?
