When approached about the situation with PS4 stock, a GAME representative told Joystiq, "GAME worked with Sony and had some PS4s flown in at the start of the week. There is a limited amount of PS4s available in GAME stores, but these are expected to go shortly, so interested customers should make their way to the nearest GAME as soon as they can."
The bottom line, then, is that the PS4 and Xbox One are both back in stock at GAME, both through stores and the retailer's website. If you want one on Christmas Day, the smart thing would be to act fast, otherwise you might be in-console-able this time next week.
For any last minute shoppers still struggling with what to buy the gamer in their life this Christmas – help is at hand at GAME. GAME has worked closely with Microsoft and have arranged for thousands of extra Xbox One consoles to arrive in GAMEs stores in the next few days, from today, meaning that gamers will still be able to get their hands on a console for Christmas. Available in store or online at game.co.uk, hurry these will go quickly!
