But according to new system specifications released this evening, those rumours were wrong.
The updated specification sheet [posted on NeoGAF], denotes that the PlayStation Vita includes 512MB of main memory in addition to 128MB VRAM. That's contrary to rumours that suggested the Vita would have just 256MB of RAM.
While it's hard for us to get excited by technical mumbo-jumbo, it's worth noting that the current PSP has 64MB memory. Exactly.
