SOC track editor?

are there infos somewhere about how the track editor of the SOC project is supposed to work?
will it be grid based and you can drag and drop track parts onto it? or will it be a bit more advanced with a real curve editor (spline or something) and where geometry will be generated according to those curves?
just curious.
