GameStop has released US pricing information for PlayStation Vita memory cards.
A 4GB card will cost $29.99, 8GB will cost $44.99, 16GB will cost $69.99, and 32GB will cost $119.99.
By comparison, Gamestop sells 2GB, 4GB, 8GB and 32 GB memory cards for the PSP at $18.99, $37.99, $50.99, and $125 respectively.
However, memory is expected to be more important to the Vita, with Sony choosing to launch retail and download versions of games on the same day.
The PlayStation Vita launches worldwide on February 22, 2012. There will be a Wi-Fi model and a more expensive 3G-enabled model available, priced at £229 and £279 in the UK, €249 and €299 in Europe, and $249 and $299 in the US.
The UK launch line-up includes Motorstorm RC, Uncharted: Golden Abyss, WipEout 2048, ModNation, Racers: Road Trip and Everybody's Golf. Facebook, Twitter, Flickr and FourSquare will also be available at launch.
