>One rumor is that MS is secretly doing Office for Linux.

I don't see how they could possibly come out ahead if they did this. There is already Star Office (close?), and AFAIK, thats free. And on top of that, most people I know that use Linux, use it because they do not want to use MS stuff. Though, just cuz they're not making money, doesn't stop MS :-) but I don't think they'll make any marks, much less the a big one.
