In an interview with Bloomberg, Sony’s Kazuo Hirai said that Japanese customers will have the Vita in time for Christmas, but that U.S. consumers will have to wait until early next year.

In a report last week, Develop Magazine the CEO of first-party Sony developer Novarama said that the Vita has about “10 times the RAM of the PSP,” meaning that the Vita has about half the memory that was rumored at launch. While Sony never released information on how much RAM the device had, it was rumored that the Vita would pack a whopping 512 MB of internal memory.

The CEO of Novarama, which makes games for the PSP, also implied that the Vita does have less RAM than was originally intended, but said he doesn’t believe it will affect game development.

“It’s actually good for developers to work under constraint,” said the studio’s CEO, Dani Sanchez-Crespo. “Generally for Vita, we still have a whole lot of headroom in terms of GPU power, CPU power and indeed RAM”
