I seriously doubt that he would be giving anything away if there's any chance of some new faces coming in given the amount of stick he's taken with previous attempts to sign the likes of Gow and Thomson, he's learned to keep things a bit more low profile now with the Goodwin deal a prime example of not making anything public until the deal has been finalized.
If he doesn't mention any potential names that he's interested in then it's not so disappointing when they don't come off as the fans haven' t been given the info to build up expectations.
