EA might be looking into the possibility of releasing. It is worth noting that EA had previously confirmed that it would be releasing seven Switch games over the 12-month time frame in June 2020. June 2022 is only couple of months away, and we've seen six confirmed games since then which includes Apex Legends this week.
Then there's one more thing to go. However, considering the Madden's release schedule each year, EA could potentially be waiting until the inevitable Madden NFL 22 - as opposed to an Madden NFL 22 port - as they generally release in August. Either way, let's just make sure it's not another old edition, or is it?
