I don't think Sony is the one to blame for the lack of a fresh approach, as Jim put it. Sony is first and foremost a hardware manufacturer, so naturally you will see an emphasis on hardware in their own event. What did you expect, a launch lineup composed entirely of new IP's? As romantic as that sounds, it's a scenario that probably belongs in a parallel universe.
Don't give up hope. New ideas will come, and new IP's will be developed, as they always have. Their "birth" is just usually a bit... temperamental. It requires a certain amount of faith (or madness if you prefer) on behalf of publishers to greenlight something new and targetted at a "core" demographic, while fully backing it up. It's rare, but it still happens. The most recent example of that would be Dishonored, a game that can surely be considered a niche title, compared to what sells these days, backed up by a shit ton of marketing. They gambled, and from what I know, it paid off. There's more where that came from, as long as we, the consumers, continue to support new games that are actually good.
