According to the department store, the gaming console is just one of a number of gadgets that are being requested by newly married couples. Other popular items include Apple iPods, HD TVs and digital photo frames, which have replaced the more traditional silver photo frame.
John Lewis also said speaker systems for iPods and other MP3 players are also a popular wedding list item.
"Two years ago, the top 20 products on the Gift List were exclusively traditional items from linens, kitchenware, china and glass but, in the second half of last year, the Wii Sports pack made it to the top 20," said Tracey Yates, senior analyst, Gift List at John Lewis.
