I think IDW has been pretty silent about what's going on with MLP. They really haven't commented on it on way or another. Which could mean that they're losing the license. Or it could mean they're waiting to be a part of big relaunch that Hasbro has planned. It's impossible to say for sure until someone finally says something.
For what it's worth, there are no MLP comics in IDW's September solicitations. Not even reprints. Which makes me sad.
Captain Kirk, Casey Jones, Street Sharks, Twilight Zone and Harbinger all launch in IDW and Valiant's Full September 2025 solicits.

But, they also don't have any Sonic that month, either. So, it might just be a off month for IDW. They had 3 reprint collections solicited for August, for comparison. Although, they were all G4 comics, which might say something. (Other than, y'know, there being 5 times as many G4 comics compared to G5.)

Maybe we'll get some news at San Diego Comic Con? (July 23-27). Companies do like to announce things there. I don't know if we should count on that. But, it's not impossible.
But, at least we still have Wild Manes! Good ol' Wild Manes is keeping the board alive! At least...for a little while. Supposedly, they only made 40 episodes, and we're currently on episode 34. So...we might only have 6 more episodes of Wild Manes, too. Then the drought will get REALLY bad. But, that's 3 or more months away. That's tomorrow's problem.

But, yeah, we do desperately need more pony. As goes pony, so goes the world! We all know what happened after G4 ended in 2019! Then G5 ended in 2024, and look what happened right after that! Hasbro, you have a moral duty to give us more quality pony content. Or else the world shall fall to DOOM! On your heads rest the fate of the world! We are currently at the lowest pony-levels in decades! Only PONY can save us now!
