How has it progressed? Like a one-legged dog in a tar pit. Since the initial release, it's gotten very underwhelming updates, and of those - several of the changes seem more the result of an OCD complex than necessary ones. There have been a few bug fixes, and a couple of new data items available, but not nearly enough to be worth noting - especially considering it's been a year.
Now, I'm willing to entertain the idea that RoI is taking up dev time, so I'm not quite ready to chalk it up to being yet another abandoned project. However, if we don't get some nice new shinnies with RoI, I've got no choice but to assume that Turbine has abandoned it, thus abandoning it myself - until I'm shown otherwise.
