Regardless of whether the Dalian fab is creating 3D NAND, 3D XPoint, or both, the IMFT relationship must be like an open marriage, with all new products subject to the partners' whims, though I suspect most of the infidelity lies on Intel's side of the bed given its non-participation in 16nm NAND. After reading this article I wondered about the level of cooperation with 3D NAND, but the first link below shows that IMFT is still in play there. It doesn't add up; why would Intel manufacture the same thing in an Intel-only facility? Either Intel expects customers to beat its doors down with demand that cannot be handled via IMFT or it is planning a special version of either 3D NAND or 3D XPoint.
