Canon is fluid. They dropped the years from the birthdays some time ago, and the games themselves aren’t even in chronological order. I keep wondering when they’ll make a game that comes after Street Fighter III (and uses the parry mechanic).
Not punched up like this new Street Fighter, but Double Dragon Neon was a solid improvement on the old formula. Definitely a better way to go than Double Dragon 4 and Super Double Dragon (which is also Double Dragon 4).
