The extension integrates your Magento 2 store with the Klarna payment service.
The extension will be released when I will want so.
The source is on GitHub: https://github.com/mage2pro/klarna
Examples of the Klarna’s Checkout page:
How’s it going with the Klarna extension, will it be released today? 
No, I have shifted the release date to December (and could shift it again in future) because now I have more profitable projects.
The USA or United Kingdom merchants can help the extension to be released faster by providing me test credentials for the version 3 of the Klarna Checkout API.
Hi Dmitry.
When you plan to release Klarna Checkout for Magneto 2 and how much it will cost?
On githut you mentioned that you will release 2017-06-04, is it still realistic deadline?
Thanks
It will be released when I will want it.
But anybody can get it in the 2 weeks timeframe by ordering my custom payment gateway integration service.
