PS4 support?
In the meantime Mr Gillett said Skype was exploring how to offer 1080p "super-high definition" video call resolution to other devices apart from the forthcoming Xbox One video games console.
Since the standard would require extra processing power, he added that tablets and laptops were set to gain the facility ahead of smartphones.
And he would not rule out the software coming to Sony's PlayStation 4 which will compete with Microsoft's machine.
"We've worked with Sony for a long time," he said. "Skype ships today on the PlayStation Portable amongst other cross-platform devices that we deliver to, and for the last few years we've also been shipping versions of Skype that run on Sony TVs.
Skype runs on the PlayStation Portable and Vita handheld consoles, but has not been announced for the PS4
"We're obviously not party to their pre-release [PlayStation] hardware road map [but] we're committed to cross-platform."
Mr Gillett would not comment on leaked documents suggesting the US National Security Agency had been able to spy on Skype video calls since July 2012.
The Guardian quoted one memo as saying: "The audio portions of these sessions have been processed correctly all along, but without the accompanying video. Now, analysts will have the complete 'picture'."
Microsoft previously declared that any changes it has made to Skype's systems since acquiring the business in 2011 "were not made to facilitate greater government access".
