It’s been rumoured for a long time, but Microsoft has officially revealed a new Zune – the Zune HD. Due on sale this Autumn, it will offer a 3.3-inch hi-res screen, a built-in HD radio receiver, and a full-screen internet browser.Meanwhile, Microsoft is also taking its Zune brand to its Xbox 360 console. Zune will provide TV and films for the videos section of the Xbox Live service, with more features due to be unveiled at the E3 games show next week.There’s no news still on when (or even whether) Zune HD will go on sale outside North America, but the HD radio feature doesn’t bode well on that front. We’d heard rumours that Zune would be crossing the Atlantic for Christmas this year, but if true, that would require a model without HD Radio. And while they could stick DAB in for the UK market, that wouldn’t then be able to be sold elsewhere in Europe.
