According to a My Little Pony website, the next round of Happy Meal toys from McDonalds will be for Cyberverse, and they will be released next month in at least three countries - Russia, Italy and South Korea.
There are eight figures in this set, with robot modes of Optimus, Megatron, Bumblebee, Shockwave, and Windblade, and alt-modes of Grimlock, Starscream and Bumblebee. (looks like Bumblebee will be the focus in this series again, with him being featured on promotional images, and having two toys in this set)

The last lot of Transformers Happy Meal toys (for RID, with figures and masks), were released in quite a few countries globally, including here, so we might see these here too in the next few months.
