There is a third option, that his predictions are true but predict something other than the complete end of earth. His doomsday predictions could mark an upheaval or large loss of life (but not complete). If that was the case, then this allows for predictions to continue past 2012. To be honest, this quote is sloppy work.
Your quoted portion of the Nostradamus page explicitly includes the phrases "predicted an apocalyptic event" and "world does not end." If something other than the "end of the world" were at issue, then maybe you would have a point. I suppose a desperate proponent could craft a claim wherein some non-world-ending cataclysm is front and center, but then we would be addressing that claim instead, likely right back to asking where the claim was made and how exactly it relates to some specific event in a specific year. However, that isn't the case, despite your apparent desire for it to be otherwise.
Also, I was disappointed to see no mention of his prophetic sketches and hoax-interpretations of them being discussed. It did feature in Nostradamus 2012 documentary by History Channel.
'The great star for seven days will burn, The cloud will make two suns appear: The great mastiff will be all night howling, When the great pontiff changes his land.' (Century 2, Quatrain 41)
Like all of his quatrains, this is so vaguely worded that you can, with the right spin, claim that Nostradamus predicted nearly any event! For example, the quatrain above could be easily construed as a supernova. Look! Nostradamus predicted SN1987A, the 1988 election of George Bush (The Great pontiff being Reagan), and the defeat of Michael Dukakis (the great mastiff). See how easy it is?
Almost invariably, 2012 proponents who quote Nostradamus rearrange the quatrains to suit themselves. Since the quatrains are so vague, they can be interpreted to mean anything. Examples of this abound on the internet.
Now what was this about "prophetic sketches?" Same point applies. Hand-waving criticism ain't gonna impress anybody here.
