My thoughts are they have dragged their feet for 5 or so years in getting done what should have been completed by 1999/2000 (after AK bridge was first refurbished). Anyway, I do not foresee any major expansion on the order you suggest for a fairly long time (10 or more years, probably) - the New SIRR will serve Howland Hook Terminal, Visy Paper, and the Waste Transfer station (perhaps I am mistaken, but it looks as if transfer buildings are almost completed to the West of the Staten Island Expressway, right North of Fresh Kills - those metal-sided 'Butler' buildings - if so, then those buildings will be idle for a year or so till the Travis Branch is refurbished completely).
Expansion I could see would involve little or no cost, such as expanding/refurbishing a spur to the remaining P&G buildings (I don't think all are owned by the PA, although again I could be wrong), some of which could be used as modern distribution/warehousing facilities (the one story metal buildings - not sure if any such firms would want the multi-story brick buildings except as offices). Perhaps if there are other firms on the ROW which may want rail service (can't think of any right now), or perhaps a team track, but otherwise don't get your hopes too high...
