If anyone is interested, it seems this is now on a general release - I saw it today in Debenhams (in the UK), along with a promotional board advertising it.
Prior to this, I saw it last week at Heathrow airport, where it was claiming to be 'travel exclusive'! That was in 125ml however, Debenhams only had 75ml.
I bought it more for collection purposes rather than quality of scent. That said, it really isn't bad. Debenhams have far worse on their shelves!
