Hard to tell. Rumours are just that, not the truth (but maybe you can add a 'yet' to that).
I suspect Dai is having to hard nose negotiations this year, and maybe quite a few players have contracts due. Some have signed already, like Jimmy Gopperth. Some have not, maybe Wadey is one. So, you have to know that Dai wants to keep him, and will have made as good an offer as he can. Wadey has clearly not accepted it, otherwise we would have heard weeks ago.
The thing is, his agent may be telling him he can get more. But that is not true. Dai has made his best offer, and knows Wade does not want to accept it. I can't blame him wanting more money, because that must be the reason he hasn't signed yet. Could be that these rumours are coming from his agent.
