There is really no need, as some people have said, It would be a waste of development money since MSOffice is already the industry standard and is great on OSX.
Office (or at least its proprietary file formats) are undoubtedly (and unfortunately, given that they are not open) the industry standard. And Office is fairly good. However, performance between Office on the PC and Office on OS X is considerably different. Try running a large spreadsheet in Excel between the two - X loses out. Try scrolling through large documents in Word - X loses out. Try moving a PowerPoint slideshow between XP and OS X - the file conversion is abject (printing falls to pieces, font spacing, line spacing etc do not convert).
An open file format, plus a few Apple R&D dollars could materially improve an Office suite. Look at what Apple have achieved with KeyNote, not to mention Safari.
