>>20910924Event legends are never released immediately. Shaymin and Arceus weren't even released untl a couple years after D/P were out. Darkrai was 2007, Shaymin 2008 and Arceus 2009.
Keldeo was a year after B/W iirc, and the other two weren't until 2012 or something. Gen V was sort so they crammed the events into one year.
