Studio Horns & Studio Strings plug-ins for Mainstage as well??

Greetings!

Does anyone know if the new Studio Horns & Studio Strings plug-ins for Logic is/will become available for Mainstage 3.3?

I'm curious, seeing that the apps are both made by Apple and feature the same plugins it'd be safe to assume Studio Horns & Studio Strings would also become available. They included Alchemy when it came into the picture so why not these?

If not, might there exist a way to manipulate the app itself in order to use studio horns/strings? <__<

This question was also posted in the Mainstage community...

Any kind of clarity on the matter would be greatly appreciated, many thanks!
