Specifics on the updated engine?

Inventory has nothing to do with engine, that's gameplay specific.

There hasn't been any major rewrites to the rendering system, instead we've concentrated how much detail can we fit in a space with it being optimised. There have been numerous small fixes and changes here and there. A lot of the 2.5ness comes down to developer workflow and stability as well, making it easier and quicker for us to iterate on our work so the overall polish of the game will be that much better.

The increased minimum specs tells a lot in terms of what you can expect, more detail, nicer textures, more objects, better lighting etc. Small tweaks that add up, also there is now colour grading which creates a great consistent and polished feel across the game.
