Today in Hong Kong Microsoft held a MSDN seminar called "The Next Generation of Development," during which they revealed some details about the WP7 update called Tango. It turns out that Tango will not be a major update, but rather a minor update to Mango focused on developing countries like China and India. It will bring improved Bing services to countries previously neglected, and as previously speculated, will serve as the OS version for lower price point devices made by Nokia, ZTE and others.
Though Tango turns out not to be exactly the next evolution of Windows Phone that we thought it would be, it was confirmed that Apollo will in fact be the next major update to the OS, which will be WP8. If Tango is only a minor update, then what is build 8200 with its new "content search" feature? If it is Tango, will we see it outside of emerging markets, like North America and Europe?
