If I am the only one interested in the hills and sheep river, I will drop that from the discussion and go with the other two. I have an extra copy of the river (assuming no one claims it from the spare parts giveaway). I imagine I can obtain sheep stickers and something resembling a vineyard and roll my own.
It's already been nearly 2.5 years since Big Box 5 and they've completely moved on to a different form of artwork, and the River (III) has already done its job for HiG, so I highly, highly doubt they're going to create a small print run of it again for hardly any or no profit. I don't really think the business world works this way even though it would be nice for consumers if it did.
Here in Germany you can get the BigBox for 30€
