I don’t have any inside info but I’m 100% confident there is much more than meets the eyes of these recent top-end security hires by Apple. They definitely are not bringing in people of this caliber just to deal with security of their current systems or to work on vulnerabilities in their software. You can bet there is going to be a major initiative announced down the road. Mostly likely elaborating around the NFC (near field communications) rumors. Look for NFC to make a hardware appearance in the mid term with revenue generating initiatives ramping up soon after.
