The concept that seems closest to production right now is the four-door Porsche Panamera, which should arrive by 2009. The issue with a front-engine Porsche sedan is that it has nothing else with which to share its platform, unless the hot as hell 928 comes back to life. The 2 door New Porsche 928 will compete with cars like Aston Martin V8 Vantage, Bentley Continental GT, and BMW M6.
