Office on iOS would certainly be a killer app, but I doubt Microsoft would want to detract from the attractiveness of their own tablet platform.
However, whether they sell office on iOS or on Windows 8 RT, they're still making money, so in the end MS might just wind up being content not dominating the tablet hardware/OS market. (I hope they trounce the hell out of those ghastly Android tablets though)
