I really hope that they borrow a lot if not everything from pandoc[1]. My only real complaint with pandoc is the table formatting, but I think fiddlosopher is adding org-mode like table support.
If you have not taken a pandoc for a spin I highly recommend you do so soon. In addition to being a great markdown dialect the pandoc tool set is the swiss army knife of text formatting. It is amazing how many formats pandoc can read and/or write.

EDIT: I spoke too soon, Fiddlosopher continues to impress. I just checked the open issues and a little less than a month ago he added "limited org-table support." Based off of the rest of pandoc "limited" probably means something like 85% to 95% :)
