Oliver Is Out for Revenge in New Mid-Season Trailer for Arrow

A brand new trailer for the mid-season premiere of Arrow has been released. The show will return with new episodes starting January 20.

For those who watched the mid-season finale we were left with quite the cliffhanger and this trailer does nothing to ease our worries. I have many theories running in my head, but one keeps sticking out, as does one word…Oracle.

Anyone else have any other theories?
