Nothing's been confirmed as yet. However, there has been speculation about it since EA announced the return of their college football series, currently slated for 2023. It would obviously be a tremendous opportunity to fill a void in the basketball gaming space, rather than competing directly with NBA 2K (which NBA Live has obviously struggled to do for a while now).
More recently, there was a Tweet from the official Electronic Arts account, which read "MADNESS LOADING", along with emojis representing a progress bar. While it could very well have simply been expressing excitement ahead of this year's NCAA tournament, it's difficult not to speculate that it might also be a hint at an announcement that will be made at some point in the not too distant future.
Personally, I'd love to see it happen. It could be a great opportunity for EA Sports to get back into the basketball gaming space. I'm also keen for anything new to play in addition to or instead of NBA 2K. In recent years I've finally been able to add some college basketball video games to my collection, and it's been a blast to check them out after all this time.
