Upcoming Microsoft Software and Service Pack Release Schedule

[JD]

Hi,

I'm looking for a way to receive notifications for any upcoming Microsoft
software service pack and releases. I receive the advance security bulletin
emails, however, those let me know of releases in the very near future. I'm
looking for something that would let me know there's a SQL Server, Windows,
.net, and/or Office service pack coming down the pipe. Does MS provide such
a service or a page I can visit for this information?

Thanks!
