After doing some poking into how long in between the air dates for every season, I found that Trollhunter Part 3 and 3Below Part 1 were 210 days apart. 3Below Part One and Part Two were 203 days apart. The pattern is 200+ days in between releases, that would place Wizards air date in February or late January. It's only been 133 days since 3Below Part Two came out. I guess that rumor about Wizards being delayed isn't such a rumor after all.
