According to Xbox 360 Fanboy, Major Nelson confirmed that there’s no official release date for the new 60 GB Xbox 360 units - “they’ll just appear in the retail channels,” he noted. And they are definitely appearing. Engadget spotted them at Amazon and others have seen them appearing at various retailers like Target. Of course, the big appeal of these new units is the extra hard drive space. Why is that important? Well, it’s certainly valuable if you’re thinking of signing up for the new Netflix powered movie download service. Revealed just last month at E3, the partnership with Netflix gives Xbox LIVE Gold members who are also Netflix subscribers the ability to instantly stream movies and TV episodes from Netflix. The extra hard disk space will definitely be an advantage for anyone who plans to make heavy use of that service.
