"Michael Pachter, an analyst with Wedbush Morgan Securities, said the delay likely won't have a significant impact on sales of the game.
"But instead of Nintendo being the clear winner this holiday, maybe Microsoft has a chance of keeping up. There's not as much compelling Nintendo content this holiday without it," he said.
