The way I see it is no, Apple does not want to add mouse support to iOS and they have a good reason for this. They really want to push touch interactions forward and to encourage developers to innovate using touch. Adding mouse support it would be like them saying "that's it guys, we went as far as we could with the touch, but now we're out of ideas, so here's mouse support for you". I don't think Apple will ever do that.
A smarter way would be to say, hey our iPads are growing in popularity and are being used for more and more sophisticated things than media consumption and there are good number of people that need a more refined way of selecting things - let's add mouse support.
