I'll say again, he's not been dead, he's just not been doing pony stuff that isn't commissions. Remember, his name is "pokehidden", so pokemon is his starting point.

he WILL finish "Banned in Equestria" since he thinks it's shitty when people don't finish stuff like that.

He also is getting fond of "Amazing adventures of Gumball" and may be going in that direction with his stuff.
