Yea, I think Jonah is supposed to be the character the old MC took over, so now he and Jayden are twins. I like the new MC's look too; he's more like an androgynous playboy type now. Also fits the dual-soul aspect he has being able to traverse between heaven and hell. Definitely looking forward to some twin action, also some vengeful hate-sex with their dad. There's a lot to look forward to with the changes.
Also hope the sex scenes will have more variation this time around than slow and DBZ fast. That was my main gripe with the game. Hopefully Snats has learned how to do some more interesting things like nipple play, maybe some frotting action with the futas/femboys, more oral variations, more positions/higher impact penetrative sex, some teasing, ETC. I know it's tempting to just use stock Illusion animations but between mods and posing you can get a lot more out of their games... Money or Morals for example (RIP to a great game) uses stock Illusion content and turns it up to 11 with mods and good posing. Hopefully Snats has taken some time to learn things on the animation front. Some of the previews do look promising though.
