Job postings are always a rick seam, and no-one is better at finding leaks than search expert, Stephen Chapman from ZDNet.
He examined some job postings from Microsoft and came to the conclusion that the much rumoured unification of the Windows 8 and Windows Phone 8 kernel is in fact real.
His evidence is below:
Résumé of a former Program Manager:
The responsibilities included program managing software update features to provide device update technology that enables end-users to update Windows Phone OS with a new set of phone features including bug fixes. In this role, I delivered a set of functional requirements specifications for the major update components to enable image updates for the next generation Windows Phone OS (aka Apollo). They are Packaging System, Imaging System, Flashing System, Update OS, Update Validator and Update Application. Also drove and tracked early investigations for the Windows 8 and Windows Phone 8 OS convergence to create Mobile SKUs.
Of course we do not know what the outcome of these investigations were, but the direction seems pretty conclusive to me.
