Unfortunately I can't provide a release date (or even an estimation) as I'm really not sure when it will be.
v2 includes a built-in template editor, to save you from having to edit the files manually, but it still needs a lot of work before it's fully ready to use.
At the moment, only the theme you see here is available (the new template system means the styles from v1 can't be carried over too easily), but I am planning to develop more in the future.
In its current state, v2 is missing methods of adding icons to links, but hopefully the groundworks are there to allow for it to be added in the future, probably for v2.1.
