You just explained how you refused a "new gameplay possibility" by sticking to the "power consoles" due to the belief that a console with less power or even an extra display just cannot give you what you believe in.
The Zombie U game wasn't perfect but it had potential and did seem to move away from the hand holding fest started last gen by Xbox360 and followed by PS3.
Given the current timing there should have been a follow-up sequel...however shifting to the power consoles only brings it into "derivative gameplay"
That isn't to say an additional display is needed but the implementation had a lot of potential for it.
