Is Tron Ares a sequel to Tron: Legacy?

Could you possibly clarify for me if Tron Ares is indeed a continuation of the storyline presented in Tron: Legacy? I've been hearing some rumors about it, and I'm quite curious to know if it builds upon the events and characters from the previous film. Could Tron Ares potentially explore new aspects of the Tron universe, or does it stay within the confines of the existing storyline? I'm eager to find out if it offers more insights into the world of Tron or if it takes a different direction altogether. Thank you for your assistance in clearing up this matter for me.
