My card details were amongst the stolen data - the Amex from the Lloyds Avios account. I'd used it to book a car rental two weeks ago, and received the email from BA this morning. I phoned Lloyds who also said "wait and see", but did give the option to cancel the card and have it reissued, which I have obviously done. I was assured that the Mastercard on the account will work as normal...
