When WO say "this is"...
they should have said "Is this"..?
And I believe the answer to be "NO!"

There is no doubt that the City of Cardiff is changing, indeed has changed over t he last 20-25 years or so, but in 10 years it will look nothing like their "artist's impression".
It never does.
I remember the metro (or St Mellons station, at least ) being touted in the early 90s, hasn't happened yet, - and it will take a lot more than 10 years to even get planning permission for all the developments they are raving about, let alone build to completion.
