Its been **ages** since I last had one of the green ones (very very dark green) they seem to have a fixation with the blue ones at present - or is it just easier to not change the stock? Even in the business check in zone though they seem to give blue ones.
That said, I have seen some with the 'new' businessclass logo (as on the most recent amenity kits) rather than with the fern motif in the last few months - just not in my sweaty hands.
