AOT 3 Full characters reveal.

I played the second game (Final Battle Edition) and I loved it, so when I saw they were going to release a third game that covers the entire AOT story, I started looking for information and saw the character list. I vaguely remember (I played AOT 2: Final Battle about 6 or 7 years ago) there being more characters who aren't currently featured on the AOT 3 website. My question is, are they going to reveal more characters, or is the list on the website the full roster?
