The 2011 Volkswagen Jetta that we get in the United States is a different animal than the one enjoyed throughout Europe. European Jettas are fitted with a multi-link rear suspension setup, upgraded wiring harness to handle more complex optional features and more upscale interior materials. Why don't we get these things? The main answer is cost.
Strong sales would show that the Jetta is in high demand, meaning Volkswagen could realistically introduce the upgraded European features by way of a mid-model change, perhaps by 2014. Will it happen? Somehow, we tend to doubt it... but a lot can happen in three years.
