I've seen a similar situation in NW England. I got my Move controllers at Midnight on launch from my local ASDA (massive superstore), queuing behind just a couple of others (I've been in a queue of around 50 people for the midnight launch of CoD WaW at this same location). I've been back in since and they still haven't even put the product out on the shelves! Apparently they have still been selling "well" regardless, although the assistant didn't quantify how many "well" means.
Today I went into my local Tesco Extra (another massive superstore) and picked up the charging station. This store did have the product merchandised (although in a poor location - I almost didn't see the display). There were about half a dozen starter packs left (looked like the space would have held 20 - 30 units) 2 or 3 Nav controllers but no Move controllers left. Sports Champions was sold out and there was only one or two copies of the other releases left.
For those of you outside the UK, Tesco and ASDA are both the same format as Walmart.
