Like the weather, it's been talked about for a while.
Given the 4 years it took to release the F3's, I wouldn't hold my breath. I recall hearing the similar things for the F3's.
It'll be good when the 2-8-0 finally gets released, but I'd continue breathing for now. If nothing else, I hope MTH uses black paint, not the 75% black SHS used.
