In an exclusive chat with Pocket-lint, Rovio Mobile has revealed its plans to bring Angry Birds to Windows Phone 7. In addition, the developer has confirmed that it's working on a 3D version of its award-winning game for compatible devices.

“We’re working on it,” said Rovio’s “Mighty Eagle” Peter Vesterbacka, when we asked him if and when Angry Birds will be available on Windows Phone 7.

It is also our understanding that it has always been Microsoft holding up the launch of Angry Birds on the platform: “Let’s just say, Microsoft has a lot of lawyers," he said.

However, now that the software giant has signed a massive agreement with fellow Finnish company Nokia over use of the fledgling OS in its smartphone strategy, it seems an appropriate time to readdress the situation.

With Rovio's undoubted success with the game on other platforms, the pressure to get Angry Birds on Windows Phone 7 is huge for Microsoft. And now that it's even transcended beyond mere casual gaming, with a tie-in with the major Hollywood animated feature film Rio, it is imperative that the game comes out on the platform sooner rather than later.

That's not to say it will be an easy alliance; Rovio Mobile and Microsoft have not always been the most amicable of business partners, mostly because the US giant unlawfully used the Angry Birds logo to launch Windows Phone 7 without Rovio’s consent, before the two companies had decided on terms of the deal.

Vesterbacka, though, now swears that's now water under the bridge and that there’s no bad blood between the two companies - hence, Angry Birds for WP7.

Aside from Rovio's confirmed work on Angry Birds for Windows Phone 7, Vesterbacka exclusively confirmed to Pocket-lint that Angry Birds will be available in 3D, but offered no details in regards to which device it will be launched on and when.

“We’ve built a lot of 3D games before, it’s not like it’s a lot of learning in order to recreate the technology with Angry Birds,” said Vesterbacka.

Seemingly, a deal with a 3D hardware manufacturer is farther along than Rovio has previously announced. And as Rovio acquired 3D gaming company Pixelgene back in 2006, it would be obvious that the company would utilise its assets to support the new wave of devices, such as Nintendo 3DS and LG Optimus 3D.

Sadly, as this is all hot off the press, there's no word yet as to an official launch date for Angry Birds on Windows Phone 7 or in 3D. But, directly from the mouth of the Mighty Eagle himself, you can be guaranteed that, "it’s all in the works."

What do you think? Should Rovio develop for Windows Phone 7? And can you imagine Angry Birds in 3D? Let us know in the comments below...
