While the world might be wetting itself over news of the brand spanking new iPhone 5, Microsoft has just opened signups for its Windows Phone 8 SDK preview.

Microsoft is releasing a full version of the SDK later this year when Windows Phone 8 devices officially hit retail markets. But for now, the company said it wants to give developers of its most popular apps a chance to check out. That means that the number of signups at this time is limited.

In a blog post, the company does offer an explanation for why its limiting signups of the preview SDK:

“I know that many of you want to know why we simply don’t publically release the full SDK now. The reason is that not all Windows Phone 8 features have been announced, and our SDK includes comprehensive emulators that allow developers to test apps against a wide range of Windows Phone features. We recognize that this is a different approach to delivering tools than we’ve taken in the past. Our goal is to generate as much Windows Phone 8 excitement as possible to attract new customers when phones go on sale. This is one of many steps we’re taking to help give you what you (and we) want most.”

Microsoft is accepting signups for the SDK preview until Sept. 17.
