Not been keeping up but having looked back at the last few days a couple of points.
I was told at the dropin that they would go to tender with the consultation plans (dating from ... (Way back)) - the detail didn't needed to be sorted out until (or by the time) contracts were signed.
And here's the thing, to paraphrase "the tender is all about ability to deliver the tram. The tramworks are by far the major part of the works and the streetscape is not that tricky". Maybe that is why they haven't included options at this stage.
The key things for Leith Walk are the local business issues and the 4 lanes of traffic - I'm not clear how closely they are connected.
Currently "local businessess'" need for parking for passing trade etc and deliveries are taking priority over space for active travel. The businesses also have concerns about loss of business during the works and the tram project are working with them on ways to mitigate this, including "redistribution" by cargo bikes and possibly cycle rickshaws etc.
So, as with Roseburn, the businesses fears need to be reduce d and them persuaded that active travel is viable and beneficial and a compromise reached (with segregated cycleways).
The "we need 4 lanes or there will be traffic chaos" is the other challenge.
Both of these should be solved outside of the tram project and then they can just be given the brief to get on with it.
Hope this helps.
