But that doesn't really matter. Releasing Office for the iPad is not only about additional revenue. It's also being done to protect existing revenue and market share. Microsoft needs to fend off Google Docs, which is free and works on all platforms. Releasing Office for the iPad is an important way to do that.
That will be even more important in future years. Rumors are that a 12-inch iPad may eventually come down the pike. If true, that would put it at the screen size of a laptop, and make it more likely that iPad owners will want a productivity suite. If Microsoft wants to keep its hold on the office productivity market, Office needs to be available for the iPad, and at some point, Android tablets as well.
