Newsarama spoke with Ethan Van Sciver at Mid-Ohio Con this weekend, and he talked about Flash: Rebirth. Some highlights:

But this is not just about Barry Allen’s return; this is about the Flash’s rebirth. This is the entire Flash legacy, all of the friends and neighbors, and bringing them all back and giving them a purpose and a new sort of lease on life. So even though Barry Allen has already appeared in Final Crisis, and was brought back in Final Crisis, which saved us a little bit of work, you’ll still see many long-lost friends. And you’ll be happy to see them again — some for the first time in ages.

And on Wally’s new costume:

He will have a very interesting and exciting new costume that will establish his own unique identity in the Flash Universe. When you see it, it will be instantly familiar. Nobody’s going to freak out. It’s not suddenly blue. He’s not reverting to the costume he wore as an infant, or as Kid Flash. It’s just a handy new look that fits right in, just like everything I’ve done. I just try to keep everything so that it looks like I didn’t create it. It was already there.
