I second Firefly. Heck, anything from Joss Whedon would be welcome, though he deserves his current break.

I loved Sports Night, would love to see another show by the same writer(s) directed as well as that director and performed as well as that ensemble.

I would love to see an update on the campy Max Headroom. They could totally CGI him in 3-D in a virtual environment, and make his quirks more subtle.
