I doubt it'll happen - for better or for worse, Niantic likes there to be a ton of mystery around their games. It's the same way in Ingress. It's an unpopular opinion, but I like it. Too many people want this game to be like other games.. they want all pokemon to be universally available to everyone, they want everything spelled out.. I like that we have to figure stuff out for ourselves.. the glitches suck, but I like that some spots have awesome spawns.. even if they're not near me. I love the idea of events taking place in cities and that it gives me something to be excited about.. I'm happy it took me months and months of hatching eggs before I got that final smoochem to complete my dex before Gen2 came out. I love that people who can't find wild rares can now team up with others to catch one at raids... it doesn't ruin the game for me because I choose not to or can't find enough people sometimes. I'm just having fun playing a game I enjoy and I don't dwell on finding things to be angry about.
