Seen this on Facebook on the Pokemon Go page:


Professor Willow has conducted research and made some major discoveries! Trainers may notice fewer Pidgey, Rattata, and Zubat, and an increased variety of other Pokémon. It was also discovered that Pidgey and Rattata no longer hatch from Eggs and Eevee now hatches from 5 km Eggs only.


Not sure if it'll effect the current eggs we have or just new ones we get BUT thank god, sick of bloody Pidgey, Rattata amd Zubat spawns and even better Pidgey and Rattata, no longer hatch from eggs and Eevee from a 5km egg!


Also a upcoming date: (no release date)
