As the year progresses, look for key upgrades of Office, SharePoint, BizTalk, SQL Server, the various components of Dynamics and a bevy of others. These products all build on the new versions of Windows. More importantly, many of the new releases are designed to interact with each other, hence offering cross-selling opportunities.
WRONG! It is not about interaction of programs. It is the Microsoft way: Create dependencies in products, so that customer need to upgrade or buy the other product. Lock them on your platform and earn, earn, earn ... Over and over again. It is exactly the opposite of open systems.
