Latios and Latias leave the Tier 5 raid spot on June 5th. Next up is presumably three months of the Regi-trio. We may even see a return of Ho-Oh like we did Lugia after that, but once that all is complete, Gen 4 should be the next release of Pokemon!

Pokemon GO generation releases are events that are always a major milestone. It's a huge attraction for anyone who is familiar with the Pokemon released, and the Diamond and Pearl generation is very well remembered. Having been the first Pokemon game on the insanely successful Nintendo DS, Gen 4 includes many new evolutions for previously released Pokemon and a bunch of new type combinations.

This list is of the ten Pokemon in the next release that will be most relevant to battling and raiding.
