Well there is a video of a NIN in full iLvl 110 gear (+115 weapon) who's doing 520 DPS on a training dummy (with group buff and buff food; no other outside help) over the course of ~3 min. This indicates that Ninjas may currently be about on par with MNKs in terms of DPS. But as the exact equipment of said NIN is not known, that parse may probably be the result of full overmelded 110 gear in a low accuracy setup, whereas I've seen MNK vids doing as much as 517 in non-crafted 110 gear (+115 weapon) without group buff or food. So MNK might still be slightly ahead, but not by much.
