It's a nice and friendly article that you wrote there. And you're right, it won't be long until we know whether there will be a 10.8 or something else. I guess next year's WWDC will already shed a light on that.
My opinion: There's a reason why they called 10.7 "Lion". It's the king of beasts, there can't be anything after it. The next Apple OS, under a new family name, will merge iOS and OS X. And it will only allow the installation of software from the Apple AppStore, of course. The first announcement will be on next year's WWDC, the release in the summer of 2013. And I hope that I'm wrong about iOS and OS X being merged and about the AppStore being the only way to install software on that platform, but Apple's next moves have been very predictable lately.
