Technology keeps on rolling...
Some notable FACTs:
Penryn
1600FSB Bump SSE4 3.2ghz is the target Higher IPC (Therefore, higher performance over Conroe) Large Virtualization performance gains (IE, Apple will be wanting these) 6 mb L2 cache dualcore & 12mb L2 cache quadcore
Nehalem
Nehalem by 2H'08 Up to 8 cores per chip Up to 16 threads per chip (Hyperthreading) No more FSB, serial point-to-point interconnect (Common System Interface, aka CSI) Integrated DDR3 Memory Controller Some Nehalem cores will feature a mid/low end integrated GPU
Suffice to say, it's an extremely refined, tuned, and slightly changed die-shrink. Penryn will outperform Conroe chips to a small degree, before the SSE4 advantage is factored in.
Most interesting I thought, was this part:
Intel EDAT: the End of the Multi-core Clock Speed Disadvantage?
Intel also talked about its "Enhanced Dynamic Acceleration Technology" which is effectively integrated overclocking based on load. If you are running a single threaded application (or a multi-threaded application that's predominantly using a single thread), Intel's EDAT can power down the second core and increase the frequency of the working core to maintain the same thermal envelope at all times.

Edit: If you own AMD stock, I suggest you fasten your 5-point safety harness at this time...
Appended:
Something to keep in mind: Unless your board can easily support a 1,600FSB overclock then don't count of plopping Penryn into your current board. Even then it may not work if the manufacturer doesn't issue an updated BIOS, and they might not since the board isn't designed for a 1.6ghz FSB in the first place.
After that, it's a fairly safe bet that everyone will need STILL both a new board and new DDR3 RAM for Nehalem chips. Unless Intel decides to use a dual DDR2/DDR3 IMC....
