    No roadmap on the language itself. However, considering the next version of AX which is slated for late 2014/early2015 still has X++ support, we're in it for quite a while longer at least.

    Considering how much lines of code there are in the standard application, as well as third party solutions, as well as customer customizations, removing the X++ language is tricky and controversial. Now that X++ gets compiled into CIL, it seems likely X++ will stay around for a very long time.

    I also think that X++ will be with us for… longer than I would like. Compilation to CIL is a cool thing, but the language itself is not expressive enough (comparing to modern languages) and it will never get such attention and care as C#, for instance. To mention only few things, I really miss proper exceptions, generics or real delegates.

    Maybe the future of X++ is to script together components written in more expressive languages - .NET Interop from X++ and VS projects in AOT lead into that direction and it's actually used quite often.

    The proxies in AX2012 also allow another approach - to write code in C# (VB) and easily use objects defined in X++ without actually rewriting them. That might be a way to gradually leave X++.

    Nevertheless if you look at the technology behind Code Upgrade Tool, it doesn't look impossible to really rewrite a lot of code…
