Cardiff moving back to the old Arms Park?

Iv'e read in a few places that Cardiff are considering switching back to their old ground the Arms Park. Personally I think it's mistake because the place was falling down when they left it and I cant really see Cardiff forking out for it's maintenance over the last season while theyve been going to the new Cardiff stadium. Secondly why on earth did Cardiff RFC and Cardiff Blue Birds build a new stadium when the Millenium stadium is right in the middle of Cardiff City centre and is one of the best stadiums in the world?

Cant see it happening, although I understand that many within the organisation are unhappy with the deal with CCFC - but there are a lot of things preventing them moving back.

This rumour was around last year too, and nothing happened - cant see it happening this time, unless there are larger financial issues than just player budget...

If the Blues, as the capital city team, really want to build for the future then their long term future has to be the CCS, how on earth would they accomodate all those Ponty fans otherwise?
