In fact, Imran Khan said the direct would be a "big one." I'm not sure if he is reliable. Maybe it was just his opinion and thought the stuff there was extra hype, but, most likely, he either got leakbaited or just doesn't have accurate info.
Tansut leaked Cloud the day of the direct, masked it as a prediction, and made it a cryptic message. With Erdrick, he's outright saying that he is in and leaking this long before his reveal (if he is in). He doesn't really have an accurate enough track record, so I don't find any reason to believe him.
