Communication with Microsoft Sales about MM2

I tried dozens of way to get an email address of the Sales group to ask if
Microsoft has any plans to update or replace MM2 and when.
I sent an email to Customer Service but they reply that I have to discuss it
with the Microsoft Sales and Information (MSI group).
Anybody has their email address. I could not find it in the website.
If sufficient inquiries come to them about MM, they themselves may start
talking about it and something may be started.
