I ordered mine on the 1st of July.Received my confirmed BW today of 38.Delivery expected mid -late October(ish).

That's still better than my order, I ordered middle of June and it's still with the factory, no confirmed BW yet

I read a VW dealers post on the TDI sub forum.He reckoned on an average 18 week for the GTD.

I know the GTD sells a a whole lot more than the GTI,especially with fleet orders etc.
I think if i hadn't got something concrete today i was going to cancel it.I just hope that VW UK mean what they say.Especially now i've got it in writing.
You should e mail them tomorrow.Or Tweet or whatever.They were certainly ahead of my dealers info.I reckon the dealers just check the( out of date) Tracker available to the rest of us.
