Doctre81 on YouTube discovered the job posting "Online Software Engineer (C++ - Madden" in November of 2020. One section of the job's requirements calls for two years' experience in "Microsoft or Sony gaming consoles". Although it may not seem like a lot, previous EA jobs listings did not mention Nintendo in their job requirements.
At the very least, EA could be investigating the possibility of a launch. It's important to remember that back in June 2020, EA confirmed it would release seven Switch games over the 12-month time frame. June 2022 is just a few months away and there have been six confirmed games in the past few months, including Apex Legends , which was announced earlier this week.
