I've given up hope that there will be ever an update and learnt to live with v1.x. However, that's just settling. As soon as I find something better, I'm gone. I bought Espresso with the hope that supporting that would encourage a lot of development but MacRabbit has been pretty slow on the improvement side as well (as shown by the sparsity on their blog http://macrabbit.com/blog/) so I've had to make do with TM since it feels better and more natural than Espresso for now.
