Experts - SAP XI Roadmap for feature versions?

Hi All,

Did any one know where to look at what is SAP Roadmap for XI feature versions, and support?

I am also looking for volume of message handling (says 100,000/hour) but little bit white papers/articles in terms of this ?

Appreciate all ur help.

thanks,
