As someone who, quite literally, checks for any new signs of Huahwi every day, I want to pass on some personal thoughts.
First off, I'd like to write about Mineorama.
Before I took my MC break, I specifically remember talking to him about my experience in Minecon. I do believe he purchased tickets to Mineorama at that time. If not, he at least expressed great interest, as he resides in New York. As I said, however, if he did purchase tickets, there
is a chance we might hear from him during that time, seeing as if he already planned on going, he would be sure that finals/anything else didn't overlap during Minorama.
Hmm, interesting. Sadly, he technically doesn't give a definitive answer as to if he's going. It's clearly implied, however.
EDIT:
He confirms it here, however this is many months beforehand.
Unfortunately, there's still the possibility that something unexpected happened to him. I believe he's 19-22 years old. I know for sure he's in college.
For those of you, especially OP, who mentioned his progression through friendships, going from regular users to "popular" people, especially with a YT, I show you this:
That's when we started playing with each other daily. I'm sure he wasn't anywhere near popular on YouTube, and he was just started to become known as a great player/pvper. I stopped playing SG for a few months (started playing again at the beginning of this month) at around late March. Rather unfortunate, I didn't really talk with him for his last weeks online. The last interaction we had was literally retweeting/favoriting a tweet we were both mentioned in, around early May.

Huahwi's channel was exploding with subscribers, for an MCSG YouTuber. He definitely could have made it to 100k from MCSG/Hive. From there, he can branch off into other MC stuff and eventually other games. This is my opinion, however.
Blamph Makes a great post on the matter, as he not only is a reliable source, he crafts logically developed paragraphs which efficiently and effectively convey necessary information.
