"Understanding the trends, architecting and piloting the implications for existing and new products and evangelizing [the] vision are the key aspects of [his] job."
understanding the trends - kind of goes without saying
evangelizing the vision - yes, that's what strategy does
piloting the implications - ok, you lost me there.
I can guess at what this means; Microsoft has hired IBM's WebSphere, DB2, Tivoli and Web services guru and he's going to look at tech trends and make sure people understand what changes need making in products because of those trends and maybe hit them over the head to make things happen. But it's more a vague, it feels like it ought to be this, amorphous inference than actual, y'know, understanding the words.
Hiring a new tech guru - $X thousand
Hiring a new tech guru *before the competition gets him* - $2X thousand
