I'll happily eat my words if they do but it would cost them billions.
They would have to take everyone's phone off them and then either refund them or give them another phone to tide them over while they fix the problem.
I can't understand how a bumper doesn't fix it as the antenna is now insulated by the rubber so it shouldn't matter how you hold it then

I reckon they will provide a software update to fix the Algorithm calculating the Bars to display and then possibly give free or heavily discounted bumpers.
