This makes sense. Given they were advertising earlier this year, and given XBC2 was undergoing localisation and sound recording etc earlier on this year, it's safe to assume at some point in the last 12 months Monolith Soft have started their next major project.
It doesn't necessarily guarantee a 2019 release from them, but I think another Monolith Soft game by the end of 2020 is a safer bet. If it's a new project that deviates from what they've done with the Xenoblade games, it might take longer to get it together - plus at least some of their staff are on DLC duty for XBC2.
