Having followed the rumors about a new iMac update in the next few months a worrying thought has also popped up: will it still have a DVD Superdrive (or better yet: BlueRay burner) and Firewire 800 or is this on the verge of being considered "outdated technology"? I need both. I'm considering the most powerful 21.5" built to order model. I hear the updates are expected to have a matt screen (or option for that) which I think is great, but what other changes are expected? And what about cost in comparison to the current model?
