This is the first article about released Creeper World 3 that I have seen or found so far, from Rock, Paper, Shotgun: http://www.rockpapershotgun.com/2014/03/31/it-does-belong-here-creeper-world-3-creeps-on-to-steam/
Sorry if there'a already a thread like this on the forums, couldn't find any fitting topic with quick search.
If you see news or reviews about CW3 please post them here :)
