Europeans (and Auastralians) will have less space than the rest of the world. At least on PSV. That is, Sony decided not to sell the (rather expensive) 32GB memory cards for PSV in Europe, as reported by Kotaku.
It is unclear whether the most capacious memory card, which will be sold in the U.S. at the dizzying price of 120 bucks, will ever come to Europe. For now, Sony has said that there are no plans to launch 32GB memory cards in the old continent, but the company could always change its mind in the future.
