Bob Arum talks about Rigo vs Loma in the December, skill wise it's the fight of the year, even maybe of a decade.
But yeah, Canelo vs GGG is the most hyped fight. Canelo is not dangerous at all for GGG imo, he can't brake him. He will try to outbox him, but he doesn't have great jab and still not very good on his feet (though much better then couple of years ago). GGG will cut the ring, eat couple of Canelo combos and drop his bombs.
