Can't see it myself tbh. They're nice enough, but I can't see them being coveted in the future. Also I don't think CW will ever really be a, 'collectable' brand.
I just watched a used (albeit mint) C15 Henley Automatic sell on ebay for £212 including post. Considering you could buy a new one for £255, I reckon the selling of a minter for around 83% of the new price is a pretty positive thing for the brand.
