I agree mate - this is the odd thing for me, that he made a significant gesture in bailing their US tour at the last minute, and hasn't followed through given the circumstances. It would seem that all the talk (I believe mostly from Swansea ITKs) about the political shenanighans with the Swansea owners has muddied the waters considerably. Yet if he does hand in a request, a) I doubt that will change the fee they will ask for at this stage and b) there would be a strong suspicion of tapping up.
Maybe he just sits it out...
