So, what's the latest? Well, you can now access the elevator that services the lower floors (1-59) of the Shinra Building. It's still in a WIP stage right now, but it ought to be finished by next release.
There's been some small updates to 61 in addition to it housing some new, surprising... occupants ;)
Finally, there's a door on 59 that will allow you to travel to a magical floating elevator above the outer plates and look at the city (and the Shinra Building) from a new perspective. The city doesn't look anywhere near as impressive as I'm envisioning, so don't worry, it's not final!
That's all for now, your comments and [constructive] criticism are welcome :).
