The chances are extremely small. There are three scenarios where this would make sense:
- If there was a specific market that required it. It would also need to be a large opportunity since developing a new platform and diluting existing platforms need significant upside. The only such market is the US, but there are better options available, namely Android that have better potential and Android is treated as a toxin by Nokia (see metaphor).
- Specific users. Windows Mobile used to be justified for business users, but Windows Phone is not targeting business users.
- The last option would be “strategic” i.e. Microsoft paying Nokia for using the OS (directly or indirectly through marketing co-spend or other symbolisms). I don’t think Nokia is desperate enough yet.
Although it’s never prudent to say never, I just don’t see any logic for Nokia to add to its bill of materials for phones while facing price pressure.
