AIB or BOI are unlikely to offer current account mortgages anytime soon. They have huge market share and make a lot of money from the existing set-up.
As there is less money to be made with these accounts, only the smaller Banks who are currently trying to win market share are likely to offer these.
Unless AIB and BOI begin to lose significant market share I would not be expecting any such changes. This is unlikeky in the near future due to the reluctance of people to move banks.
