Next mobile event – Nokia World will be held in London on 26th and 27th of October this year. So, we are expecting that there will be present all new Windows Phone 7 devices by Nokia. In that way, Nokia will have enough time to put on sale their smartphones before the end of the year. First phones that we expect are Nokia W7 and W8. They will be the same like X7 and X8 but with higher resolution and Snapdragon processors. Also, W7 and W8 will be powered by Windows Phone Mango.
