Yes it does. It covers MeeGo on the N900 (and why there isn't an answer yet *edit* worth noting that since it's a reference developer platform, there's no technical reason it won't run. So even if Nokia don't officially endorse it, it'll work out just fine*endedit*). It covers Maemo5's future (in that it has one at this point). It covers a lot of the stuff you mentioned, and that flippant answer makes me think you didn't even bother to read the table of contents.
