If you read between the lines on the last few statements Microsoft have made on this matter ,they intend to ship with internet explorer and not wait for confirmation from the EC . they have said they will be offering a choice of browser so users can change if they wish . as production is already well underway, I dont see it being any different .
but as nothing has been confirmed so far we are all having to guess . personally I believe we will get the same version as everyone else with a choice of browser after initial setup.
