Something I've just been thinking. When the REmake Remaster was announced, a month later we got the news of Revelations 2. Also, Lost In Nightmares was finally made available to PC. These two old games had two key characters for Revelations 2: Barry in REmake and the reference to Alex in Lost In Nightmares. Barry hadn't been seen in a game for a long time and Alex was only mentioned in files in DLC, so some fans wouldn't have heard of them.
We've just had the announcement for RE0. E3 is in one month, with RE7 rumoured to feature. Could Rebecca play a role?
I understand Rebecca was in the REmaster too, but this might be a way for fans who don't know that much about her to become more familiar with her.
This is literally just a theory I've come up with so don't take it seriously. I just thought it's something fun to discuss.
