One ex-Sony boss has admitted the excellent PS Vita was a "great" console, but just arrived "too late".

The PS Vita was revered by critics as a powerful handheld with great potential, but was held back by a lack of software, expensive entry point and the mobile gaming's sudden surge in popularity.

Speaking during the latest episode of IGN Unfiltered, Jack Tretton – the former CEO of Sony Computer Entertainment America – revealed his thoughts, in hindsight, of the PS Vita.

"Now that I don't work there anymore, I think internally it was: 'This is a great machine, it's just too late'," admitted Tretton. "The world has shifted to portable devices that aren't dedicated gaming machines."

It was the PlayStation Portable – aka the PSP – that really stole the show when it came to PlayStation handheld consoles.

It did the job of offering a console-like experience on a handheld and was also surprisingly popular with older gamers.

Tretton went on to call the PS Vita a "nice machine" that unfortunately launched "at a time when very few people needed a dedicated portable device".

Despite the PS Vita's shortcomings, Nintendo has seen incredible success with the 3DS family – with Pokémon Go even boosting sales by over 200% for 2DS and 3DS XL consoles.
