M25 Speed Cameras

I've just had this emailed through by a colleague who is, apparently, in the know about these things...

"As of February 15th all cameras on the M25 between J10 and 15 (A3 to the M40) are going digital and having their threshold set at 80mph (true speed) and will be active 24/7, (as opposed to peak times only/93mph at present)"

Essential info for anyone who rides / drives on this section regularly and wants to keep their licence if it's true... Be careful out there people.
