If you pre-order the Caprotti version, which incidentally is only available as a Hornby web exclusive you have the option to cancel anyway if the product is not as described or indeed not what you expect.
A "Win Win" situation in my books which works.
Additionally, no money is taken from a prospective purchaser until the item arrives in stock, so giving those who wish to cancel the option.
Remember, no one's forcing you to pre-order !
