Basically, Muncher is still looking into it and its still a work in progress, his trying to do it properly and get proper permission but I'm not sure if he is aware about the recent ban.
However Munchers always said if others are willing to bring forward another location, organise it, do their homework on it then people can vote on the location they prefer.
There's still talks of a possible London or Cardiff CB but nothing is confirmed and just talk, but Norwich is still the only location that someone is actively working on to make it a CB location.
Think the above sums up the full thread on PP more or less.
