John Eales (66)
Has he signed for 2016?
No, but he hasn't announced that he's going anywhere either. He's on contract till after the RWC.
You seem to be making the assumption that any incumbents aren't going to be around unless they state otherwise..which is fine but it's a pretty conservative view and also likely to be incorrect in many cases.
With regards to Butler, if he's ever going to get a Wallabies berth it will probably be as a 7..even S Hoiles would be ahead of him at 8 for 2016.
