It looks like we have our Windows Phone roadmap filled out for at least the next year, as Tango has been confirmed by Microsoft as next year's minor update preceding Apollo (aka Windows Phone 8). As mentioned at a MSDN seminar in Hong Kong, the successor to Windows Phone Mango will indeed be made for handsets in developing countries -- a key method to make these devices more affordable. These targeted nations have been neglected to this point, the company said, and the Tango update would bring more Bing services to them at a lower cost. Will such a move help Ballmer & Co. achieve greater market share against Apple and Google? It's hard to tell -- we certainly don't see this update coming to Vertu anytime soon, so we imagine that's probably a good sign.
