Yikes, Not terribly impressive I'm afraid. I was happy to see that they mentioned official support for DDR2-800. They are going to need super high frequencies like that to make up for the crappy timings. As of right now, I see little reason to move away from 939 unless there are other memory controller tweaks (for better handling of 2GB and multiple dimms for example..) not to mention resolution of the cold bug, although I wont hold my breath on that one..
As we already mentioned in our evaluation of ULi's M1697 chipset, there is no need for new chipsets for AM2, and it won't affect the chipset development of 3rd party manufacturers either. Basically, every core logic product that supports the current AMD64 processor family will also support the Socket AM2 generation, because the communication path between the processor and the system is HyperTransport.
Way to go AMD

.. someone give these guys a 100% pure 1337 award for their A64 architecture already!
I have totally lost track of the number of chipsets and boards that intel has gone through.. who knows what chip works with what chipset
