I am not sure what sort of changes the developers have for that, but it's a great question! I imagine it will be another opportunity for third-party developers to step in. Busy.org and Utopian.io are two examples of interface that is already very different from Steemit (but build right on top the blockchain).
We shall see!
nobody knows anything basically it seems and if the myth-enshrouded SMTs will ever see the light of day...
