Let me explain the confusion as I understand it.
What your seeing is Office on an iPad but not intended for an iPad.
You are seeing early development for an Office product on Arm based tablets, intended for release when we eventually see windows 8 based tablets.
The development of these early software prototypes is being carried out on iPads but will never be released as iPad software, they are merely the tools for development as windows based arm tablets are likewise still in development alongside the OS.
It explains the confusion and the subsequent denial of product for the iPad.
Microsoft need an office product to be released alongside the Windows 8 tablets. Its a way of selling them to Joe Public via recognised brand recognition, and give them some differentiator from the slew of Android and iOS devices.
Do not expect to see this on the iPad unless win 8 tablets are a flop.

I love Pages and Keynote. Prefer it over Word and PowerPoint.
Now to get Numbers to do more functions and handle larger spreadsheets I can ditch Excel.
Pages on Lion is a disaster. Complete memory hog, and becomes very slow and unresponsive. It was never like that on snow leopard.
I pray to god Apple release iWork updates this year and soon, otherwise I'll have to abandon pages completely. I used it a heck of a lot, now I begrudgedly use it since Lion.
