I think you are right, Maybe I need to look more closely. The bmi site says:
"For departing customers, Star Alliance will open its largest lounge in the entire network in Terminal 1 in June 2008. The 1,650 square metre facility will be for all First and Business Class passengers as well as for Star Alliance Gold Card holders travelling on any of the member carriers from Terminal 1."

and also says:
"The bmi international lounge will move from its current location at Gate 14 to a new lounge area at Gate 5. For our gold diamond club members travelling long haul, the opening of a new Star Alliance departures lounge in June 2008 will introduce even greater flexibility to your choice of facility for unwinding and relaxing before a flight."

Havent been near LHR since early april after a T5 experience and have been avoiding LHR deliberately, but inbound tomorrow and through twice next week, so I will look around.
