Last week there have already been various leaks about the upcoming Build version 9888 of Windows 10 which will be probably available at late January and this will be the first Build version where the name shifts from Technical Preview to Consumer Preview, what means that Windows will be in a more mature status then. However, according to WinBeta and the Verge, with the Windows 10 Consumer Preview there will be presented also Windows Phone 10.
Microsoft recently began with the roll out of Windows Phone 10 to partners for testing purposes. The first kernel version which has been brought to Microsoft partners was version 8.15.xxxxx tough we would expect kernel version 10.0 like the kernel version of Windows 10 Build 9888 but it is not yet confirmed when Microsoft will use this kernel version also for Windows Phone.
Still, Microsoft is going to release the Windows Phone 10 Preview along with the Windows 10 Consumer Preview if we can believe these current leaks. Tough it is not sure yet if the Windows Phone 10 Preview will be released to all Developer Preview participants at this time or if this will follow some time later this year. About the features of Windows Phone 10 there has not been leaked anything yet, so we will see what happens and hopefully get some more information before the official event in January.
