If you're talking about this interview from Famitsu. He never said anything about the Compilation, which technically would be "old" characters seeing how it's been ten years since that fiasco started. He simply said no "new characters" which looking at ports and remakes of other JRPGs, it tends to be trendy to shoe-horn in a new character to mix it up for old fans. So I would say its still a possibility this game will tie into the Compilation unless you're referencing a different interview.
