So in less than two decades a lot or classic heroes like Bruce Wayne Batman, Clark Kent Superman, etc will all be 100 years old. I believe that’s when things go public domain ( I might be wrong here - this stuff is confusing ! ). What are the chances we see a more permanent “promotion” for several characters that would fall under this? Dick Grayson is barely any newer than the two I listed, so would this be a time where say Tim Drake becomes Batman and it actually sticks?
This way they could theoretically still keep stuff under copyright since for example Tim Drake didn’t show up until the 1980s so wouldn’t be public domain until the 2080s. Same goes for others from that time period - so maybe one of the Superboys getting a permanent promo, a new Wonder Woman, etc.
