My implication was that if the 4e Rogue was moved to PF and was called a Rogue, it would be a Rogue, and would be just as non-magical as the 4e Rogue, in response to the 4e Rogue would never be called Rogue because being from 4e automatically makes it magic somehow(despite 4e explicitly stating the Rogue isn't magical).
Well, the 4th Ed Rogue does use the Martial power source, which is described as non-traditional magic.
