It is very worrying for all of us with pensions in £s. However, be a little wary of predictions from Currency companies who are always keen for people to buy “before the rate goes down further”. Even the £ is unlikely to be a one-way bet forever and I have read several commentators who expect things to stabilise Feb-April 09 at a higher level than now.
I stress I am not an expert or a predictor but it is easy to get carried away at the moment.
In addition nothing would make me wish to spend my retirement in the UK.
