Oh, I bet there would be a very large market for MS Office for Linux in the corporate IT space.

Proof?

[Question_Assumptions]

Do some web searches on "Microsoft Office" and Linux and you'll find (A) that there are commercial products that allow users to run older version of Office on Linux, (B) that IBM has expressed interest in the idea, and (C) quote a few of the articles talking about corporate adoption of Linux on the destop talk about companies not switching because of Office or caution against switching because of Office. All of that suggests quite a bit of demand to me. But, hey, believe whatever you want. If OpenOffice ever gets good enough to challenge MS Office, it will be too late.
