Thank you for your responses, they're much appreciated..
I'm not too concerned about 73H as I know EK use different equip codes to identify their aircraft, I have access to Galileo so I'm familiar.
What I can't find on the link provided by Emirates777 is the config info for the B777-300er (73H). I have a feeling we're going to have the dreaded sleeperette seats and I will not be happy if this happens on a overnight flight...
Thanks again
