However, one Sony item did manage to sell out over the weekend: Sony’s proprietary memory cards for the PlayStation Vita (16GB and 32GB) both managed to sell out despite consumers complaining about the higher prices and lack of flexibility. Then again, it’s not like they had a choice. With Sony’s strict rules about one PSN account tied to a memory card, I’m thinking that many consumers shared to purchase a Vita and invested in additional memory cards instead. But let’s wait for official numbers before we determine the console’s success.
