No.
It would easily run on either console. HPL isn't the most powerful engine around. Only that FrictionalGames' aim is to support HPL3, or rather, HPL3 is supported by PS3.

Right, the engine is not very powerful, but it requires a lot of strong hardware to run on high settings. Even Amnesia runs extremely slow when playing with 32x (or more) SSAO samples. And HPL3 even got a lot of additional features.

An engine doesn't need to be powerful - the best games have totally outdated engines. But it's not just about the graphics. There is other stuff like the physics that needs a lot of hardware.

Consoles, even the "Next-Gen's" are just powerful like a 500$ PC.
