After everything Amar has given us, and given how often he is correct about information regarding GT, I highly doubt his credibility would take that much of a hit.
But yes he did mention something about "all being revealed no later than E3" in his first cryptic post. I have good reason to believe that he's right and that he won't let us down...
However, even if he is not right, I, and almost everyone else here, appreciates what he has given us in the past, and what he continues to give us now, and like I said, I have no reason to doubt him, and I'm sure most people can forgive him if he is wrong...
Or, all of us read his encrypted posts incorrectly, and would therefore, be our fault.
