Sony has thus far been unable to ignite PS Vita sales, but interest in the handheld could suddenly spring into life, Sony Computer Entertainment Europe's senior business development manager Shahid Kamal Ahmad has told Gamasutra.

Regarding Sony's five million sales forecast for the Vita, Ahmad said: "Sometimes things can happen and they can dramatically change the evolution in terms of sales of a platform."

"But what you can never do is say 'We're definitely counting for this kind of increase.' So you can put plans into motion and say 'We're trying this approach, that approach,' and if something comes off, it's going to be fantastic."

Asked if the five million figure was essentially a worst case scenario, Ahmad replied: "Yeah. I mean, I'm probably not the right person to speak to about corporate performance - I'm such a tiny part of the whole organization.

"What I can say is that looking back at the performance of different consoles over the course of history, sometimes you've had slow starts which have been suddenly sprung into life by a number of activities."

He concluded: "What you don't say ahead of time is, 'Oh this will and that will happen, and suddenly we'll have a massive spike in sales.' It's not the sort of thing that companies do."
