Depends on what you mean by power, I suppose. Nova is Turing complete, so there's that.
One big difference between Nova and -most- logic languages is that "forgetting" things is a normal part of operation. Nova is also forward chaining, rather than backtracking.
The end result ends up with Nova programs being something closer to an interpreter in a lot of cases, and writing inputs for said interpreter.
So, Nova doesn't do as much on your behalf as Prolog does, deliberately trying to be easier to reason about, and to have more predictable performance characteristics.
There are two major things that I'm curious about:
Price point: How much is this going to cost per unit? I'd imagine it's going to be much cheaper than the other current gen consoles
Battery life: If it doesn't get more than 1-2 hours, or else come with some way to extend the battery life via an accessory, it will be kinda underwhelming.
That being said, this is a very intriguing idea, and is a good focus on an easy to understand concept. Funny image: Two people playing on a Switch with the controllers snapped onto it, doing some top down game like air hockey or something.
