Satellite image: http://cimss.ssec.wisc.edu/tropic/real-time/europe/images/xxirmet7n.GIF (look at 47N/23W)
The current (0000 UTC Oct 7th) image suggests a very tropical-ish appearance to go along with the cyclone phase space diagrams suggesting a subtropical or barely tropical structure.

This is most likely a case for a potential post-season upgrade. NHC is watching it, but unless this persists at such a high latitude -- a good 700km or so north of Vince from 2005 -- it's not likely to get classified now.
