Moore's Law: Another casualty of the financial meltdown?

Given the exponential increase of fabrication costs, the global recession and credit crunch, one may ask if Moore's Law is financially viable beyond 22nm node. Can we justify the return-of-investment (ROI) for continuous scaling beyond 22nm? Shall we consider other alternatives for integration, such as silicon-in-a-package (SiP) or 3D integrations?
