Meego will will be merged out of existence. MeeGo will become Tizen. Tizen is a software platform and a mobile and device operating system based on Linux and other popular upstream projects. According to Intel, Tizen will build upon the strengths of both LiMo and MeeGo and Intel will work with MeeGo partners to help them move from MeeGo to Tizen.
The Tizen project is hosted at the Linux Foundation and offers an operating system and an HTML5 development environment within which applications can be produced to run on multiple types of hardware. The Tizen application programming interfaces are based on HTML5 and other web standards, and it is anticipates that the vast majority of Tizen application development will be based on these emerging standards. Tizen will provide a robust and flexible environment for application developers, based on HTML5 and Wholesale Applications Community (WAC). The Tizen SDK and API will allow developers to use HTML5 and related web technologies to write applications that run across multiple device segments, including smartphone, tablet, smart TV, in-vehicle infotainment, and netbook. So the application development is expect to shift from Meego/Qt now to Tizen/HTML5.
For those who use native code in their applications (small percentage of the applications), the Tizen SDK will include a native development kit.
Tizen sounds an awful lot like WebOS to me. Why do we need more Linux OS? Will this really replace the ones it is combining together or fragmenting the market more? The situation in mobile Linux field seems to be pretty similar to what happens at xkcd:Standards comic to standards.
