Another online store has Rise of the Beast toys listed for release on April this year... despite the move being pushed back a year to mid 2023.

If the new movie toys are indeed coming out in April, it definitely means that they were in full production before the decision was made to delay the release of the movie... and it would just cost too much to sit on the toys for a whole year.
We've seen it before, and unfortunately it hurts the toyline and Brand as a whole. The toys don't have the "advertising" of the movie, so they don't sell well enough for retailers to order more (if there are later waves), and a larger Brand like Transformers would then be weighed down by dead stock that retailers have to discount (lose money) just to get rid of them.
