"Resident Evil Revelations is an all new Resident Evil title with over 20 hours of gameplay, and cutscenes beautifully rendered in fear-inducing 3D. A true console experience on a handheld device, Resident Evil Revelations is an epic title that offers both a single-player campaign for that classic survival horror gaming experience, and an additional RAID mode that can be played cooperatively or single player. To handle all of that data Resident Evil Revelations requires a 4GB cartridge, resulting in a higher price point." - Capcom spokesperson

So...a long explanation to say that the card size has to do with price. I'm honestly not that miffed with the pricing. Are you guys feeling a bit slighted? Thanks to Battlestriker123 for the heads up.
