Thats speculation and not close to even the knowns. Milkshake can receive 2 years. The no fault argument is here a myth as other players took a different view and opted out. It falls upon the player. Given the way the players involved were complicit with EFC in attempting to derail proceedings etc I can't see any leniency offered.
He has served a bit over 4 months only as voluntary suspension.
The the likelihood if Wada succeeds is a ban of around 18months. Nothing has come to light regarding any of the 34 restarting any suspension. I wouldn't expect to see him at all next season. Bargain.
