The approval for the Himalaya doesn't mean it'll be marketed in US, but there's a great chance of this happening, since T-Mobile will market it in Europe as the MDA.
The new new T-Mobile MDA will include the new operating system Windows Mobile 2003 Phone Edition, a better display with 16-bit support (65,536 colours) and builtin camera.
This device will also be market in Europe by O2 as the XDA II.
