Personally I can't see, in the present environment, that it is really necessary for the industry, to put the 225 into service again. The 189 and the 175 can easily cover the gap the 225 left. More in UK (Aberdeen) than in the Norwegian sector, where they basically have been using the 92 only, which gives them no cover if the 92 is grounded.
Half a year ago, I was quite sure that the 225 was done in the Northsea, but not so sure anymore. It would be sad to see the 225 in service again, and the passengers not feeling confident about it, only driven by Airbus motivation to get it back.
