In recent days, two Nokia PowerPoint presentations have been leaked, one of which exposured by WPArea.de presentation is up to 25 pages. It shows that there is an overlap between the WP 7.x and WP 8 timetable.

Microsoft may not update WP 7.8 to WP 7.x, but why Nokia added a text box after WP 7.8?

Microsoft will use the OTA (over-the-air) to offer a variety of small patches and complete the OS update. It is also one reason why the many smartphone users are optimistic about WP8. But it is hard to say if the facts will be like that, especially after the intervention of the operators.
The WP Russian official Twitter page said Microsoft support for WP 7.8 is up to 18 months, which will continue to mid-2014. But no matter how it will be updated it can not be compared with WP 8, WP 8 can support multi-core processor, a microSD slot (on some models), and also can accept the OTA update and supports the NFC, which the WP 7 can not do.
