So, what is your question again? Where you can find the dev info? See point 1: on github if you are a developer.
If - as a non-developer you want an update on the progress, point 1 & 2 plus joining their slack will help, and/or read the latest update - v2 is about to come out!

1) developer info: https://github.com/swarmcity/ - updates every day + http://thisis.swarm.city for the team
2) community information: http://slackinvite.swarm.city or https://www.reddit.com/r/SwarmCity/ --> very much alive
3) roadmap: https://www.reddit.com/r/SwarmCity/comments/7es9cv/swarmcity_roadmap_next_major_release/ -> they don't give an exact dates to avoid pumpers & dumpers like you.

Plz stop your FUD, you clearly have nothing better to do, sad.
