Just visiting Serebii.net and I noticed they're saying Pokémon Ranch might be out THIS WEEK because the official UK Nintendo magazine has a review of it and is stating an "out now" status on ranch. The magazine isn't due out until Friday, so it sounds like it might be released between now and Friday. So keep an eye out for it just in case it is!!
As for me... I still have no Wii damnit.
Miiiight take a quick walk into town tomorrow, after midday, to see if Argos have one. Knowing my luck, probably not... but if they don't I'll check places like Currys/Comet and what not.
Depends on the weather really.
