A new and larger attraction is being developed at a new location in Cardiff.
A statement from BBC Worldwide says
We have consulted with the City Council for the past 18 months regarding our plans and we are confident that the new attraction’s features, size and location will draw many more fans to the Welsh capital from across the UK.
The current Cardiff Exhibition has drawn over half a million visitors since it opened in December 2005 at the Red Dragon Centre, Cardiff Bay. It will run until 27th March 2011. The Land's End exhibition will close on 2nd January 2011 and the Newcastle one on 31 October 2010.
Further details regarding the new Cardiff attraction will be published shortly.
