Meant to post this up when it came out, but just in case anyone was worried, all the DC TV shows should be safe for renewal this season:

Network president Mark Pedowitz is "optimistic" that Arrow, The Flash, Supergirl, and DC's Legends of Tomorrow will return next season, he told EW at the Television Critics Association's winter press tour Sunday.
"At the moment, it's a little too soon," Pedowitz says. "We're noted for announcing at winter TCA that we're picking up shows, we just weren't ready to do that yet. A couple more weeks [and] we'll probably get around to it. I'm pretty confident we'll see them all back."
"We haven't renewed anything yet," Pedowitz notes. "We're not quite ready to do that. We're a couple of weeks out. I'm pretty confident a lot of the [CW] slate is coming back. We're just not ready to make that a formal announcement yet. It is only Jan. 7. It's just a question of the board and I getting together and having a discussion about it. We just weren't ready with the holidays and this came just days later. We'll get there. I'm confident most of our schedule is coming back."
