Monolith Soft job listing has fans wondering if another Xenoblade title is in the works

We recently shared news of Monolith Soft looking to hire new employees, but today's information is separate from that. Monolith Soft is looking to bring in some more people for a new RPG project, and it's being handled by Production Dev. Team 1. That's the same team who created Xenoblade Chronicles, Xenoblade Chronicles X, and Xenoblade Chronicles 2. If the other team is working on a new fantasy action game featuring an all new IP, what could Team 1 be up to?
