According to this article (see also this video), Microsoft and SuSE have announced a partnership. According to the article Microsoft will actually be selling SuSE Linux. I didn’t hear that in the video, but certainly they’re going to be working to interoperate more closely. It remains to be seen exactly what that means or if it’ll be good for SuSE and Linux as a whole in the long term. Novell’s shares have spiked by 20% today (Novell owns SuSE), so it’s certainly good for them in the short term.
Here’s the press release with more details.
