New Supergirl Movie?

I've been keeping an eye out for news about a potential new Supergirl movie for some time now, but nothing seems to be happening.

Has anyone heard anything about this in a while?

You hear rumors now and then about who is going to play Supergirl but there has been nothing concrete in a couple of years.

I don't think there will be any movement until Superman Returns is released next year.
