Nobody knows or cares about Weidman. Silva/Bisping is the best/most interesting MW fight to make right now IF Silva is going to fight a middlweight. The fact that anyone could think Silva is ducking Weidman of all people is quite hilarious.
I'd personally like to see Silva/Hendo again. Since Sonnen will be fighting Bones, and we all know the Silva/GSP or Silva/Bones superfights will probably never come to fruition, Silva/Hendo would make sense.
