According to Microsoft’s Joe Belfiore, Skype is “definitely coming this fall.” He said this whilst speaking at MIX 2011 which started on Tuesday.
With the extra phone integration features that developers are getting next May, you will be able to call your contacts using Skype. The Phone Integration features include Multitasking, Contacts and Calendar access, and also access to the Camera.
Will we see a front facing camera?.. Time will tell us.
