$10B? lol. what are you...high? $6-7B is even ridiculous. First, remember that the Nortel patents were bought for $4.5B by 6 companies! Microsoft, Apple, Ericsson, EMC, Sony and RIM. So the patents were obviously not worth $4.5B to a single company, but rather around a billion, hence Google's $900M stalking horse bid.
If a deal is reached, I see it going through in the $60-$65 range. jmho.
