Unfortunately, no exact release date has been revealed so far. Mr. Robot is an excellent example how a television network is tracking down a response by the target audience since this show can't boast with the impressive television ratings.
Indeed, the third season premiere has garnered only 0.681 million viewers with a 0.30 key demo (P18-49). This figure is even lower in comparison with a second season finale (0.85 million). However, in spite of this descending trend, USA Network pays attention to other indicators, such as a reception from the viewers, as we suppose. In fact, the reaction was brilliant, given the statistics by Rotten Tomatoes. According to their data, the third season of Mr. Robot has a score of 8.23/10/92% among critics, and 4.6/5/93% among the viewers. These figures look impressive. If we take a look at Metacritic, we also discover pretty favorable numbers, 82/100, 7.8/10, among critics/viewers, respectively.
So, we'd explain the decision on renewal relying on the reaction of critics and viewers. Another reason could be the storyline of Mr. Robot. It appears that there remained a lot of things to explore in this show. Summing up, we believe that Mr. Robot has unexhausted potential thanks to its brilliant conception, topicality, and a perfect script. Thus, USA Network likely regards this show as a long-term project.
Also worth noting that Mr. Robot touches the vital questions of the modern "digital society," such as peer-to-peer networks, torrenting, cyber attacks, BitCoin, etc. This show has an endless source, because of the rapidly developing technological progress. According to Deadline, the motto of Season 4 is "Integration."
