New Nvidia chipset in November, MCP78 with DX10 IGP

We're looking at three different models for difference price points. There will be a U, S and D (seems like Nvidia is thinking a lot about money) version of the MCP78, with the U version having the fastest integrated graphics solution with the S model being slower and the D model lacking integrated graphics all together. The pricing information doesn't seem right, as no-one is going to pay US$70-80 for a chipset, although this almost seems too cheap for a board based on a brand new chipset.
