we all do..but I suspect John remains rather quiet for a reason. There was an interview I will never forget around the time AToF came out talking about either him or the label looking for him to do more, but then like a couple of years later, I couldn't find it anywhere (or my memory was bad about the details). What I concluded after that was the EP very well may have been it.
He's a family-man. Busy doing the 9-5 thing (or whatever schedule he keeps). And doing music isn't exactly a simple thing for his schedule.
