As it says.
My friend phoned me this morning to say that Virgin (where he works) in Stirling got six Wii in this morning. They haven't been put out on the shelf yet as they are awaiting instructions on how to bundle them from HQ but i've just been up and the manager let me have it as long as i took something else (copy of Fargo special edition for £6 :-)).
Apparently most stores in Scotland got a drop this morning, so i may guess this would mean UK wide as well? As i said as of 3.30pm today they weren't out on display or on the shelves but were waiting to be 'bundled' so if you go in and ask you'll be in luck.
On another plus point they also had around 10x nunchuck controllers for £19.99 which are also very rare at this time. Whacked on a 10% student discount and a very nice afternoons work indeed.
On the bad side no copies of Wario Ware, Zelda, Call of Duty 3 or Wii Play / extra remotes.
