I'm pleased to say that I can answer my original question as to whether TomCats are still being built.........yes they are!
Found a dealer ad for a 2012 today, although I suppose it's debatable if it's a 2012 or a 2011.
The interior is trimmed in the manner of the 2009 pics I've seen (in which a thousand mice have given their coats to line the walls), and locker doors are now wood rather than teak trimmed.
I
think the entrance to the front berth has been enlarged, and the three hatches inside have now been mounted the correct way up, i.e. they drop down so they stay open.
Finally, the switches on the instrument panel have been changed for different models (which I'm not sure I like).
Other than that though, I think it's a huge improvement to the interior.
However, I'm sure there are other differences which the experts will be able to point out.
