No, we're going to lose more and more ports to the reality that they will become obsolete, replaced with wireless options, cloud services or simply shrunken versions of their former selves.
The concept of the MacBook Air is that there is a market full of people that want as thin and light a notebook as possible. Those people don't give a damn about ports. They want as much of a standalone device as possible.
Speak for yourself. If I can't have a DVD drive, I need to be able to hook one up. I also need to have a way to put things on there without networking. USB isn't obsolete, wireless doesn't always work. Storage will never become obsolete.
