Abrams is the Nerd King of all of us.. Star Trek and Star Wars, and they'll both be worth watching!! Maybe a Trek vs. Wars film in the vein of AVP...I don't think Abrams is going to abandon the Trek franchise any time soon. He's only doing the one Star Wars for now. I like how everyone is freaking out, though.. I don't see why he can't do both. Wouldn't you want to do both if you could?
I don't see as many Star Wars fans freaking out about this on popular Wars message boards like stardestroyer.net. God some sci-fi fans can be incorrigible.
