I didn't know there was such thing as 'HD fanboys'. Yes people may call each other fanboys for supporting different systems as everyone has a different point of view. However there is a significant different between HD and SD, HD being far superior. I don't think there's any disagreement in that, so no 'fanboys'.
When he says HD fanboys he just means 360/PS3 fanboys. I think it was just a shorter way to write what he ment. Dont think its had anything to do with HD in general. At least thats how i took it.
BTW hes right on.
