They never officially said they were on hiatus, but they're not active in any way right now. They've said in interviews that they're not even thinking about new AFI until the Blaqk Audio album and touring cycle is done. They're contract with Interscope is filled too, so I'm sure that'll be another setback/delay once they do get to work on something new though.
Davey & Jade did a few BA shows and keep promising a record soon, but their claims have never really led to anything. They're looking for a label to release the new BA album that's been complete for a while, but it seems as if they might have found one.
Hunter is on tour with/a member of(?) Matt Skiba and The Sekrets and Adam is in a band called The Reckless Kind
