Just a heads up really for anyone who is still desperate to get their hands on Wii Fit. I called in on the off chance about half an hour ago to see if they had any in. The display was empty so I asked one of the staff if they had any. By complete luck he said that they had approx. 200 delivered this morning and they hadn't unpacked them yet. When I went to the counter to collect the game they had boxes full of them. They're still unavailable online but I can't imagine that Cardiff Bay is the only store to get them in today so it may be worth phoning any near you to see if they have them in too - i've linked to the store finder on the website.
TIP - priced at the rrp of £69.99 but if you are a Gold Card member there is a £5 off £20 spend on games in the mailing - so £64.99.
