There are Nikon seminars though at £30 per session (not for the day) they are not cheap compared to Nikon's free event at the Velodrome in November. The morning session on the new pro cameras is probaly the most interesting to me. I might go to this if some of us could also meet locally. With 100 miles travel each way for me (from North Yorks via M1/M62)I would prefer to make a day of it if coming to Manchester.
Photography is a bit like archery. A technically better camera, lens or arrow may not hit the target as often as it could if the photographer or archer does not practice enough.
