With all of Verizon's recent changes to meet Job's rules on how to sell Apple products I cannot see anyone looking at a 2 year contract as a great deal when the difference is $70 out of pocket. I am still undecided on the Bionic vs ThunderBolt and I have compared them both pro and cons alike. Besides I tend to move more quickly from one phone to another selling the old to pay for the new.
To really benefit from the Tegra 2 Dual Core we need Gingerbread/Honeycomb and its going to launch with 2.2 (hopefully 2.2.1) so that means late summer for 2.3 or hopefully 2.4 which is updates to Gingerbread 2.3.
Still if the phone isn't coming out until April I cannot see any reason why they are not launching it with 2.3, they have months to get it done and given past Moto OTA updates and how well they went I would be suspect on this going any better.
Just food for thought.
