In the past, I often looked up to find that “328 minutes of Tell Your Tale” content was expected to air, with four 22 minute specials included in the plan, while others would simply be up to 5 minutes. So, having looked up what that meant by actual hours and minutes, I found that the total is 5 hours and 28 minutes.

Having multiplied the 5 minute runtime by the 9 released thus far, I’ve found that 45 minutes has been used up. Add that to “The Blockywockys”, which is 22 minutes, and it can be confirmed that up 67 minutes has been used, totaling 1 hour and 7 minutes.

Subtract 67 from 328, and you get 261, meaning that only 4 hours and 21 minutes is left. All before G5, as far as we know, officially concludes its run.

I expected Hasbro to run the G5 show three years more. This... I don't know what to say to this.

Well, they haven’t exactly been offering much anyway. It’s been the same thing over and over again. “Comedy-based” storylines that are neither funny or showcase much heart, lack of character development and morality, and repeated catchphrases that openly prohibit story-progression.

There is that leaked memo mentioning a new 3D series, though there's no indication of whether that will be "Make Your Mark" by a different name or G6.
