My crystal ball is not operating correctly right now, so I have no opinion on what WILL happen.
I do have an opinion about what SHOULD happen, however. While I cannot argue numbers with the business folks, as a historian, I will claim that the engine has value beyond--and different from--its monetary value. There is such a thing as historical value. I am not talking about running in excursion service, which I accept as being impractical. It is impractical to run much better suited engines in excursion service right now, at least (see Frisco 1522).
But that the engine is ill-suited for restoration to running condition does not mean that it holds no value to us as part of our history. Whether it should win a competition for monies to be used for its preservation as an artifact ('stuffed and mounted," if you will, but much of our history is stuffed and mounted--no one is flying the Spirit of St. Louis or the Apollo 11 CM these days) is an open question, but I think its claim to a slice of the pie is at least as valid as claims for many other artifacts.
Unfortunately, all such debate is currently moot given the position of the owner. We can only hope it will survive long enough for the possibility to appear.
