Has Witten announced his new geometry?

  1. May 12, 2015 #1
    I had vaguely read somewhere a while ago that Ed Witten was developing some sort of new geometry where the only true, fundamental objects were worldsheets. Perhaps I'm not correctly remembering the idea but I think it was something like this. Has he announced this recently? I can't seem to find anything online.
