There's a little bit on this new series at Broadcast Now. Apparently it will be produced by Anna Cox with Michael Mosley and Jean-Claude Bragard acting as executive producers. Cox and Bragard worked together on the 2006 documentary series The Miracles of Jesus (pictured), and Bragard has been involved in other religious documentaries for the BBC since at least 2001 when he produced / directed Son of God.
There's also a press release from the BBC which mainly seems to focus on the Beeb's partnership with Greek broadcaster SKAI Television, but it does have this to say:
Religious co-production Bible will be a six part series featuring the most important and iconic Bible stories. Each episode will use drama and CGI to bring the stories to life – emphasising their humanity, the miraculous experiences and the epic encounters.Various sources have stressed that The Bible will be a big budget production, though figures are a little sketchy. I also seem to recall hearing that this was a 13 episode series whereas these pages say it will be six hour long episodes. I'll post more news as it comes along.
It will be an accessible, entertaining, informative and intelligent guide to important passages in the Bible.
