Default [Q] New version of Touchwiz

I'm wondering if anyone knew if the new version of Touchwiz will be an S5 exclusive or if it is something that will be included in the new Kitkat stock rom?

Kind of early I know, but still have to ask.

It's nothing groundbreaking but it is a bit fresher. If not I'm sure someone will find a way to extract it to our S4's...
