Didn't he "yep" the earlier rumor too?
Sounds like confirmation bias to me - he gets credit when he's right, but doesn't get dinged when he's wrong. For all we know he's schizophrenic and walks around saying "yep!" all day.
No he didnt, in fact Wednesday he said he was going to an early lunch because he wasnt expecting anything cool in his email, which is when everybody realized that the invitations were not going out that day. The only thing he has yepped about with regard to the ipad mini was that there were going to be two events one in september for the iphone and one in october for ipad mini, which is what is happening. I've been following this stuff for a long time and I dont think he has ever yepped something that wasn't true, so until he does I take everything as rumor until Jim yeps it and then I plan accordingly.
