Proprietary is always more expensive than mass market. Volume reduces manufacturing costs per unit. The more you sell, the more you can manufacture, the cheaper your bottom line.
If you wanted to start selling a line of orange juice in your region, your cost per unit would be WAY higher than, say, what Tropicana deals with. That's just the way business works. The problem with Vita memory cards is that they won't go down in manufacturing costs unless they start selling a lot of them.
