Sisu are in a terrible bargaining position even if talks were to begin. They are the ones in need of favour's they need to fall into demands from the other parties.
The statement's made by parties mean nothing, Higgs, Wasps and CSF can say they will talk but they don't want to yet or ever need to unless it's makes business sense to them.
Sisu going to the FA is another sign they are struggling to get a foothold or any leverage with talks. Also Wasps will already know what Sisu need to gain grants and funding.
This is not about talks, common ground or compromising this is about who is controlling the situation and manipulating the press to suit or fit a plan. Unfortunately at the minute Sisu don't have one and areally running out of time, the question is not about talks, it's really about who so talks help.
Either way even if talks are held rejections will be the excuse for failure of agreement.
