I was a direct entry into LGW Worldwide but the list to transfer to LHR WW is the same as the LHR EF one. I joined in Dec 03 and I have my first LHR WW trip rostered for next month! Thats pretty good going for BA. It must be remembered that most people in the past have had to wait for years (5 + or so) so BA is all about timing!
My personal opinion is that as BA are in the process of a huge recruitment at the moment which has been ongoing for about 2 years now the bottom is bound to fall out shortly and the wait to transfer to WW may soon increase again as number begin to even out!!!!
