And Firefly? And "name-your-Trek-series-here"? Caprica leaving you a bit unfulfilled? Me too. Re-runs are fine, but you can only watch Our Mrs. Reynolds so many times (well, not really--I can watch that one all day long) before you want something new.
io9 has a look at a ton of upcoming sci-fi (mostly) shows. Some look really intriguing, so here's hoping!
I think the one's I'm most interested in will be either The Cape or A Game of Thrones.
