The particular version of the model on eBay may be a Sam's Club exclusive, but the DC27 will be available in the UK. Ours is different, though - it has the clutch control, and it looks like the floorhead is quite different to the US version.
I was told in a January email from a VERY reliable source at Dyson UK that the DC27 would receive a low-key UK trade launch in February 2009, and it was pitched at the section of the market who prefer wheels to the Ball design. It certainly has been low-key so far, seeing as we have the promotion, but no machines!
The scanned page below has run in Argos catalogue since the Spring/Summer 2009 issue was released in February. Despite having been advertised like this for 3 months, it is still currently listed as 'out of stock' if you try to purchase one. Same goes for the online retailers like littlewoodsdirect, additionsdirect, etc.
One interesting point: suddenly, for a week or so, on all the online listings for this model, the model number was changed to 'N27'. Then, just as suddenly, it was changed back to DC27!
