HP Envy 17, dv6, and dv7 with sandy bridge based CPU

The guys over engadget show us a new laptops series from HP with sandy bridge CPU inside ,

HP just updated a bunch of its consumer laptops here at CES, and the biggest change is that the Envy 17 and Pavilion dv6 and dv7 have been kicked over to Intel's Sandy Bridge second-gen Core processors. In addition to the new chips, the Envy 17 is getting HP CoolSense cooling and switchable AMD Radeon 6850M graphics with support for Intel Wireless Display -- pricing and availability haven't been determined yet, but we wouldn't expect it to be cheap. On the other hand, the dv6 and dv7 are mostly the same apart from the processor bump, and they'll be $899 and $999 when they hit on January 9th.
