Windows Phone 8 references appear in browser analytic reports
Hitlinks has the newest Microsoft creation showing in their mobile OS market share analytics derived from browser usage. There has been nothing in February, but March saw usage of the Windows Phone 8 browser shoot up to 0.15% of the overall WP usage, meaning that there are definitely a few devices in testing lying around.
It also looks like Microsoft is trying everything in their power to speed up the development process and bring to market the souped up Windows Phone 8 with its HD screens and 1080p video capture support as early as possible. We already heard that the new Nokia Windows Phones with it are supposed to be "unbelievable", and if they are anything like the specs rumored for the chubby kid with the PureView Pro 41MP camera technology, we can't wait.
