It is very savable, and structurally sound. The Central Terminal Restoration Corporation (CTRC) has gone to great lengths to seal the building from the elements and secure the entire property from further vandalism. My dad & I try to take part in the annual volunteer cleanup of the grounds and minor maintenance.)
Unfortunately, much of the building's fixtures have been gutted - the clock was found in an antique shop in Chicago and has been repurchased thanks to a grant from Wilmers/M&T Bank, some of the art deco sconces, fixtures, etc. from the diner have shown up in a restaurant in Hong Kong. All of the marble stalls and paneling in the rest rooms have been removed (stolen), or just smashed to pieces for the hell of it.
The biggest problem is finding a viable reuse for a hulking monstrosity like the BCT, in a neighborhood that is largely residential. We had hoped the Senecas would see the value - the CTRC even put together an adjacent parcel of 25 acres for gas stations, smoke shops, etc., but the SGC wanted their casino downtown. Right now, the high speed rail facility, maybe even coupled with some sort of railroad museum (there are way more train buffs out there than I ever realized) is probably the most viable plan.
