DELL XPS 15 Frost White

Hi, I'm planning on buying an XPS 15 laptop and was wondering when the frost white model would be expected to be released in the UK. I heard it's already been released in the US since late August but can't find anything related to it on the UK website. Would really like to buy it and don't mind waiting a few more weeks but if it's not expected to be released by end of October then I might have to look elsewhere. Any help or insights into the expected release dates would help!
