As it stands right now, this will be bottle shop release. So no numbered bottles, but it is expected to be released in limited quantities. All bottles will be boxed and they will be delicious.
Best way to get some is to ask your local bottleshop if they are getting any in stock, if they are not, ask them to do so, if they don't know anything about it then they are daft. Give them your contact details, check in for updates, make pre-orders.
The price is expected to be $54.99, which for a limited run rum at 43%ABV isn't bad. Expect larger chains to have better prices, like First Choice and Dan's. None of this is confirmed, but it comes from the best people.
