We just reported about VLC player for Windows 8.1 already uploaded to Windows store and waiting for certification. The VLC team has posted an image too, which shows app in certification.
Microsoft needs to hurry here, it seems!!
Now, on asking about VLC player for Windows Phone, the VLC team has hinted about targeting Windows Phone 8.1 for the app development. They cite performance reasons behind this decision.
