According to a May 7th post on Stylzworld.com’s blog, they’re currently working on a Kindle case:

STYLZ cases for BeBook and Kindle ebook readers

We have good news for all you ebook readers out there. In conjuction with BeBook we will design some special cases for the BeBook ebook reader. Not only will we add BeBook cases and USB charger to our range of accessories but also for the Amazon Kindle ereader. For both Bebook as Kindle, the cases can be purchased online from stylzworld.com

No further information was given, but at least there will be a third alternative case on the marketplace. Here’s hoping it will be made of rubber or some other synthetic material instead of boring old leather.
