Aside from the licensed merch, we're starting to see activity from Hasbro again as well. On a Mexican toy website they secretly hid the two ponies among the images of wave 1. While it was expected that Rarity and Rainbow Dash would join the G4.5 / Reveal the Magic singles line, but with these images we get to see what accessories they come with!
Rarity will come with a light pink comb, a translucent hair band, a jewel hair clip and two hair hair elastics. Rainbow Dash gets a similar set of accessories, but with a white comb, cloud hair clip and a blue hair band with a bow.
There's also Amazon listings for Rarity & Rainbow Dash, but those are just placeholders for the time being, the images are not yet listed there. A release date is hard to say, as we're not sure on what delay the pandemic has caused with Hasbro and their factories, but we're guessing it will still be during the summer.
Thanks to Tomo for the heads-up!

Soon we'll get to see a second wave of the G4.5 Fashion Squad Equestria Girls figures, and one of those will be a set with Pinkie Pie and... Minty! It will be her first release in the Fashion Squad line, and actually her first release in the Equestria Girls line at all. Who knew that a pony that has been popular since Generation 1 could see so little releases in G4!

After a teaser campaign on Instagram the news is now officially out: My Little Pony will return to Discovery Family in 2020 with a brand new animated series called Pony Life.
The new TV-series will feature new chibi-style animations, done by Hasbro's own Allspark Animation, and the mane 6 and their voice actors from Friendship is Magic will return for this series.
The show will center around Sugarcube Corner, Pinkie Pie and mysterious potions in a Slice of Life setting. Aside from the main TV-show the My Little Pony YouTube channel will continue to release exclusive shorts.
