Brand New Trailer for ARROW's Midseason Premiere

I don't watch Arrow, but the midseason finale cliffhanger regarding the fate of Oliver Queen was such big news that even I heard about it. The CW has released a brand new trailer for the show, and I know there are a ton of Arrow fans out there dying for it to be January 21st so they can see how things get resolved. This trailer will help pass the time, as it gives a pretty good look at Laurel, Felicity, and the rest of the gang making a pretty big discovery, as well as Ray Palmer (Brandon Routh) tinkering with a new invention. Could that have something to do with the potential spin-off, I wonder? We'll have to wait and see.
