With the arrival of PlayStation Vita in February, it was expected that users would only be able to set-up one PSN account per handheld, but this week we've learnt that won't be the case, due to PSN accounts being tied into Vita's memory card. Vita uses a new proprietary flash memory card, which will launch in sizes ranging from 2GB to 16GB, and will hold your PSN content, downloaded titles and game saves. That means if you want an extra PSN account, you simply have to purchase another memory card.
The downside, of course, is that you'll have to fork out for a new memory card, which could be very lucrative for Sony. The cards haven't currently been priced, but are rumoured to cost significantly higher than existing Memory Sticks or SD cards of the same capacity. It's also believed that PlayStation Vita won't come bundled with a memory card at launch. So on top of the price you pay for the device ($299 for the 3G model, but yet to be determined in the UK) you'll also have to pay for a memory card - and perhaps multiple ones if you want separate accounts for other family members. Kerching!
