Guess it depends on how successful BvS and JL are. Cavill had an admirable start. Didn't MOS make more than the first Iron Man? And even as iconic as SM is, the character was coming off a terrible film (Superman Returns) and was somewhat irrelevant. Actually, MOS made me a SM fan again. With apologies to Reeve, Cavill is my all-time fav Kal-el. Honestly I'll be disappointed if there's not more Cavill-led SM solos.
