I'm all for new IP, but new IP are commercially very, very risky. Making another FPS basically means Killzone is dead-dead, which from Sony's perspective is like giving up a core of people that would buy it due to the KZ name.
Of course, I can already predict the responses to this:
- The core KZ fan base is now so small as to not matter.
- Horizon was a new IP, and look how successful it is!
Valid points, of course, but to these I say:
- It has been battered by Shadow Fall, but it is still there, and a even a few hundred thousand people is better than zero.
- Past success is FAR from a guarantee of future results... especially when it comes to new IP. Horizon did it, but that was in a fairly wide-open genre and at a perfect time for it. Making a successful new FPS might just be the toughest thing to pull off in the entire industry.
