There really is quite a lot of wine out there. You can't track every wine through every vintage. Sometimes this throws up surprises.
It's two years, and two vintages, since I have tasted d'Arenberg's Feral Fox Pinot Noir, and I was really rather surprised by the way it has changed. It is much, much lighter than in the past. I followed this wine from the 2002 to 2006 vintage without seeing any change from the rich, concentrated, McLaren Vale style - the anti-Burgundy, as it were.
Savoury - soy, minerals, stones - and also juicy like cherries, the 2008 vintage is still a straightforward sort of a Pinot, but much less concentrated than the 2006 was. I wasn't alone in this judgement, B said so too.
I don't think the wine is worse, or better, for the change (it's a relaxed juicy, 3+), but it is surprising, and I can imagine that people who liked it in the past might be disappointed by this year's version.
