The following websites, along with the source code and Facebook and Twitter accounts will be taken down:
www.symbian.org, www.symbian.org/cn, www.symbian.org/jp
developer.symbian.org, developer.symbian.org/cn, developer.symbian.org/jp, kernel.symbian.org
blog.symbian.org, blogcn.symbian.org, blogjp.symbian.org
Nevertheless, Symbian documentation from the websites would still be available on request and will be shipped (for a fee) on a physical medium after January 31st, 2011. Such a move hints that Espoo is betting all on MeeGo, the platform it jointly develops with Intel, for the long term. But MeeGo is still in its early stages and to see if our prediction is right we would have to wait.
