I got invite to order and of June, and they did say it's 10 week lead time for delivery, so I'm not disappointed with RS.
Also I live in a small mountain village in the French Alpes, a bit out of the way, so it's feasible it's gone missing en route, although RS still didn't send a shipping ack yet.
Oh well, have to console myself playing with a neat little MIPS board that turned up, although it doesn't have a load of GPIO pins that the PI does, which is really what I want to have a play with ;-)
