The problem with those 3 guys is they all do the same thing. Page and Hendrix are not in that same category of guitarists. So yes, they ARE still considered greats even now. I don't think there are any guitarists today that can or have accomplished what Page and Hendrix did. Hendrix did so much in very little time and Page prooved that he could keep his massive band going through good times, bad times :p

I don't think in 30 years people will be talking about the guitarists of today as much as people will still be trying to figure out how the hell Hendrix played what he did.
