Windows 7: Intel "Sandy Bridge" hybrid graphics won't support DirectX 11

Today during the IDF keynote speech Intel demoed its “Sandy Bridge” hybrid graphics-microprocessor chip, and confirmed that the standalone chip won’t support DirectX 11 graphics.
“Sandy Bridge” is the beginning of what Intel calls its “Processor Graphics” line and is the chip giant’s attempt at killing off, or at least profiting from, the entry-level GPU market by incorporating a GPU on the same silicon as the CPU. The platform is a successor to the Nehalem/Westmere architecture and places the CPU and GPU on the same die. The single-die design means that both the CPU and GPU can make use of the on-chip cache.
