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.
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 
Unlike Japan, Nintendo has not invaded the entire home consumer market here in the United States. This leads them to believe there is room for both the DS and the DSi here in the United States. The DS will no doubt be a cheaper alternative to the DSi and the DSi isn’t going to make its way to the US for some time now (well into 2009 we hear).
