I do confess that I was also hoping for an entirely new (or mostly new) fleet of AAs, given the lengthy refurb.
Short of that, I hope they get the old ones working more smoothly and consistently. If we get to this time next year, and things are already back to being pretty creaky again, that would be a misfire.
With the amount of time this is going to be down, the objective should be that it should come back looking better than it ever has.
