According to The Wrestling Observer Newsletter, plans for Wrestlemania 33 have only seen minor changes recently, but the Goldberg versus Brock Lesnar Universal Championship match has been penciled in as the last match of the night from the start.
Unless WWE does change course, Brock Lesnar is slated to win the title; the reason Goldberg had such a dominant showing at Survivor Series (and the Royal Rumble) was so the end of the feud would see Lesnar finally go over.
It was noted that Goldberg’s contract expires after Wrestlemania, but they could always sign him for a longer stretch, and this this title match likely won’t be a long one based on Goldberg’s last two.
