Any lenders reacting to Ulster 2.6%

Has anyone heard (officially or through the grape vine) if other lenders are going to react to the Ulster rate of 2.6%?
I am told that Ulster have a high volume of mortgage applications at the moment, surely other lenders must be positioning to catch up?

PTSB first to respond with 2% cash back on repayments (in addition to the 2% cashback of loan value). Who will be next? KBC, AIB, Haven or....... Ulster again?

It's not much of a response from PTSB. Limited to new customers only so as usual they're happy to have existing variable rate customers subsidise the deals for the rest of their customers.
