VST"A" with Excel
 

Does anyone know if Microsoft will be integrating VSTA with Excel
(just like Infopath)?
VSTA and not VSTO seems like a more natural progression from VBA,
especially if your application necessitates that end users create
macros that they can also conveniently debug.
I found some posts that indicate it won't be integrated but they are
pretty old so I was wondering if something has changed.

thanks,
