Once you put Skyrim on that list you basically eliminated every other option. It is true not everyone will be playing Skyrim when it comes out, I personally don't know why but there will be people not interested.
But for those who are it just means you are getting Skyrim. And while other people are renting and buying 3 or 4 games to play over the next couple of months you will probably be about halfway through Skyrim.
Skyrim is bigger then a standard game release. Its more of an event. Most gamers would rather pick up Skyrim at $60 and play it for 5 to 6 months, then when they are done with it pick up those other titles either by rental or for $30 on Amazon sales.
Personally I don't know if I will ever finish Skyrim, my philosophy in gaming has always been see a dragon kill a dragon, with endless dragons in Skyrim I am going to see alot of dragons, meaning I am going to fight them all :).
