There is some more detail available on the Common Platform alliance 32nm from the advance material put together by the organisers of the VLSI Technology Symposium. It illustrates the kind of bets that the fabs and foundries are making on the next generation of silicon, although the details are still sketchy.
With the 32nm generation, IBM and its partners expect to be able to deliver a process that exceeds the industry consensus on what is needed at that point. The consensus is summed up in the pile of documents that go by the name of the International Technology Roadmap for Semiconductors (ITRS). Taken together, the documents are effectively the guidelines for what the industry needs to stay on Moore's Law.
Scattered throughout the PDFs are tables of specifications that semiconductors should get close to if they are to be useful at a given process geometry. The numbers are all colour coded: yellow means tricky but possible; red means nobody has an answer yet, or at least one they've shared in public.
