I'd be surprised if Apple didn't "fix" these antenna issues soon with a new model (that will be basically the exact same, but not suffer from it so badly). I can't imagine Apple would continue to sell the iPhone 4 with this publicised flaw (whether you think it is major or minor) for the next two years.
They'll slyly fix it with a new batch of models, and anyone who complains, Apple can just say "this issue affected a small number of iPhone's and we will replace them".
