My fellow nerds greetings from the multiverse here. this years crossover on DCTV will be kinda big. The main shows in this years crossover is the flash,supergirl, and arrow. The legends of tomorrow will not be in the crossover this year.
I think they made up for it tho with the introduction of batwoman and Gotham city also Superman and Lois lane being in the crossover. 
The biggest surprise to me is that John Wesley Shipp reprising his role as Barry Allen from the flash tv show from the 90’s. This years main villain is supposed the be the monitor. Not much else has been revealed but the cast have posted pictures on their social media accounts from set showing Gotham city parts. Green arrow actor Stephen amell posted a picture of his self ,grant gustin,and melissa benoist sitting in front of the bat signal.
The three night crossover starts Sunday December 9 on the CW @8pm est.
