Hopes for the Masters EX 4th Anniversary?

(And the final Villain Arc)

So what characters do you expect? What events? And is someone else wondering what characters will be added to the Region-specific 5☆ guaranteed scouts? And how will the new characters break the limits of what we once thought was overpowered?

I have no idea, but I do know that they will somehow show us the most overpowered creatures you've ever seen (as the 3.5 Anniversary set the bar pretty high up).
