Nikki Finke reports that a deal has been worked out that gives Seth Macfarlane the go-ahead on reboot of TV and film versions of animated classic The Flinstones that will air on Fox, but there's no scheduled airdate yet. Perhaps there will be additional details at Fox's upfront meeting that starts in less than an hour (4pm ET).
Update: Kevin Reilly did speak briefly at the upfront about this this, it will definitely be a series that airs on Fox, but won't debut until 2013. The plan is to do updated stories, but stick with a similar look to the original, and use the original theme music. Here's the press release from Fox.
