I have been looking into this car my self as I am/was interested in buying it. However, I have since spoken to VW customer services and it is looking like the UK won't get the TCR

Here is the response I got.
Dear Mr Love
Thank you for your recent contact.
Unfortunately, the update link has been removed from the website at present. I am sorry for any disappointment that this may cause.
I have spoken with our Product Marketing Team who has advised that there are no plans for this vehicle specification to be offered in the UK in the immediate future. The reason for this is that we do not anticipate that there would be sufficient orders of this specification for the UK market. I am sincerely sorry for any disappointment that this may cause.
I hope this information proves useful. If we can be of any further assistance, please do not hesitate to contact us on the number below.
Thank you for contacting Volkswagen UK.
Kind regards
Adeel Saeed
