"Wie gaat winnen?"

Translation: Who is going to win?

[schiffmeister]

What is the difference, besides probability, between "wie gaat winnen" and "wie zal winnen"?

[KayP1603]

None, it is similar to the English: "who will win" versus "who is going to win". If you want to be very precise: "wie zal winnen" is used when you are really curious about the outcome. One's attitude might be more relaxed regarding a match when saying: "wie gaat winnen".
