My thoughts exactly. Normally when someone moves on they say why....it does not say he is quitting rugby, I would infer that there is another club coming in for him (perhaps unannounced as a courtesy by Wasps to the other club) , or he has offers from more than one club and is considering, or things are so bad at Wasps with him and Dai that being paid to be injured is worse than not being paid, which is unlikely to say the least, as paid is better than not. Maybe it is an insurance or legal thing, have there ever been contracts where they run out in Jan or can be terminated early?
