Which platform versions currently run the Zen Pinball 2 Engine?

[ENGEE]

I've wondered this ever since Zen Pinball 2's release. Ever since then, there are still platforms on which the game is just called "Zen Pinball, or "Pinball FX2", like before.

My question is, were all these versions updated with all the niceties of the improved physics engine and so on, or are they, as their names suggest, still running on the older Zen Pinball engine? And/Or has there been any updated version since that is still exclusive to a few platforms?

Zen Pinball 2 is based off of the Pinball FX 2 engine. It's pretty much a perfect port of Pinball FX 2. The only games that don't run on the Pinball FX 2 engine are Pinball FX 1 (Xbox 360), Zen Pinball 1 (PS3) and maybe the 3DS versions (ZP 3D and MP 3D).
