SamBishop: General hilariously deluded Vita fanboyism with regular insistence as fact that unspecified big games were coming in the future (for instance, asserting that there would be "plenty" of Vita announcements at E3 2012); when I asked him about it last summer via another forum, he sent over two massive walls of text basically admitting that he didn't actually have any knowledge of system-selling games coming, but that he just had faith that sales would pick up dramatically following a price drop, which would in turn lead to renewed third-party support.
The only specific software prediction I ever saw him make was stating as fact on another forum, shortly after the awful TGS 2011 Vita conference, that Capcom was bringing Lost Planet and RE to Vita in some form. When I followed up with him nearly a year later, he claimed that his source at Capcom had left shortly after the original rumor and thus could no longer confirm it.
James Mielke: Said this in
an interview in April of last year:
When I followed up with him via Twitter after TGS last year, for some strange reason, he refused to give a yes/no answer when asked whether he stood by those comments.
Heck, I'll name one of the current GAFfers I was referring to: After Sony's Vita-light E3 2012 conference, famousmortimer claimed that TGS would
deliver on big Vita announcements, and also relayed news of an impending announcement from Vita Game Heaven 2 that would
"make GAF very, very happy," claiming to know both points for a fact. A few posts later, he was
already downplaying the veracity of his sources.
I suspect you greatly exaggerate the level of inside information to which analysts have access. Heck, I'm pretty sure zomg himself admitted that he was just speculating.
