Regarding Uncharted: the genre kings have already been crowned. Just as Forza was too late to the market to attack GT's throne, Uncharted was far too late to dethrone CoD/Halo/Gears.
After a genre begins to mature, the top games in that genre take an increasingly large portion of the sales, and new IPs begin to be disproportionately punished in the marketplace. Bad games do even worse, and good ones do less well than expected, unless you are one of the chosen few. This will be increasingly true as time goes on.
