I would be in for a demo and the PRR versions.
According to Mike Wolf at York some time ago they got so few orders the last time it was announced that there is no way it will ever be produced.
Although I know nothing about the La Jolla Line, I would purchase a model of this unique and interesting locomotive. It would be a nice addition to MTH's Premier line, and something different than the many steam, diesel, and electric locomotives that already have been produced and which have been run and re-run many times. I don't expect a model of the "La Jolla" to be made. But I certainly would like to see some things like this, as well as scale trolleys, interurbans and an AMTRAK ACS-64.
Too bad that the previous offering was not a 3/2 configuration.
