Digital Spy - Sony has no current plans for multiple slim PS Vita colours or a 64GB memory card in the UK.
"Black has been, over the history of PlayStation portable consoles anyway, the most successful colour," UK managing director Fergal Gera told Digital Spy.
"So we're happy to introduce black. Might we introduce some more colours? Well, perhaps. But we're not taking that call right here and now."
He continued: "To be honest, I don't want to complicate for us and for our retailers excessively by trying to manage multiple SKUs, but it's certainly not a case of saying never. It's just saying, 'Not for the moment'."
While Gera also had nothing to "announce here and now" for a 64GB memory card, the launch of the new slim Vita will give them an opportunity to evaluate demand.
"We will regauge feedback and this is a good moment as we introduce this new device to listen to what gamers are saying," he said.
