Pokedex

Heading to DesMoines tonight hopefully to find new Pokemon. I worry that they may take them away and replace them with the 2nd gen ones before I get them all . 

Like many other game apps this is what they do. The ones you don't get within a time frame are gone for a while and only available during special events . Will this happen??? I don't know but I want to get most of them if it does.

I heard rumors or them making trading Pokemon and fighting against one another  part of this app . I hope so !
