My intention wasn't to start speculation and I definitely think there will be ample changes made due to injuries and form prior to when the protected list is picked but I'd guess:
Props (1-3): Robbo, Alexander, Slipper
Hookers (4-5): Moore, TPN
Locks (6-8): Horwill, Douglas, Pyle/Simmons/Timani
Backrow (9-13): Palu, Pocock, Hooper, Higginbotham, Mowen or Dennis
HB (14): Genia
5/8 (15-18): Cooper, Beale, O'Connor, Lealiifano
Centres (19-21): Tapuai, McCabe, AAC (Adam Ashley-Cooper)
Wing (22-24): Ioane, Mitchell, Tomane/Shipperley/Cummins
FB (25): Barnes
That would be my guess on a likely 25 protected players. There will obviously be some changes with players showing irresistable form and definitely some injuries but I think the players picked will be largely based on the consistent 2012 test players plus the injured superstars.
