RE7 Rumor

There's another rumor that I forgot to add to the consistent list of Japanese Re7 rumors;
which is that a character from a past work/title is set to appear in the game.
If this excludes anyone that appeared in RE6 so far, it narrows the options for a returning character to a select few.

It is a given that such characters like Chris, Ada, Jake and Sherry may appear or make cameos in the next game as the story endings in
relation to them were left open. So I would not think their return would be as much of a surprise compared to an unexpected character from Re1-5.

New generation numbered RE titles have been strong in male leads(RE4-RE6), so one would wonder if they'll consider putting a female character in the
leading position again, and not secondary or over-shadowed by a male character. Or, much like the classic games, allow the player to choose between a male or female protagonist to explore the game solo; and doing so may alter the direction they take, their encounters with other characters, enemies etc.

Revelations proved that you could both return to horror and feature a female protagonist and it would still sell. Although, Revelations wasn't fully centric to one character, and while Jill took the lead for a majority of the game, the story split off to the perspective of other characters involved.

When they say "of a past work", it is unknown what timeframe they are referring to. Past as in previous to RE6? Or from a classic title?

Who do we have left to choose from?
