I glanced at a few presentations and was most surprised to see predictions of the resurgence of ASIC vendors (vs. today's popular "COT" model). I'm not sure I agree, but it makes a certain amount of sense. It takes a lot of tools, people, and expertise to implement 45 nanometer chips. The proposition is that if it is possible to cleanly hand off at RTL, then the chip designer can focus on functionality, and let an implementation house focus on the tricks and traps of nanometer-scale design closure. But that's a big if, to be confident that the hand-off is of a properly constrained and realizable design!
