Exactly.
Taking into account how irrelevant Knights Landing is to Intel's bottom line, any core option except minimally improved Knights Corner is extremely unlikely.
I can imagine brand new core only in one scenario - if VPU-less variant of the same core is used for Intel's variant of Niagara. But, then again, why would Intel want to build its own Nigara when even the latest iteration of SparcT is seriously less Niagarish then the previous one.
