I still have my money on the GAL/Parking garage site.
I would really, really like to know the exact reason why this isn't already done. It seems too perfect with a rather reasonable pile of red tape to not be done. Other than price (be it the likely false rumor of GAL asking too much, or CFG's unwillingness to pay full taxes on the property or other political costs), there doesn't seem to be a single insurmountable hurdle.
I too think it will be there eventually, once CFG realizes that they simply aren't going to get a good deal anywhere on this project. I could even see them going back to the Queens site and paying off the right people, but that seems to have more hurdles than the Bronx.
They'll spend another year on the search at least, then crawl back to one of these sites and plop down the money.
