I think people would be more surprised that Nintendo would make something like that in the first place.
In the way that Astro Bot looks like something that Nintendo would make, Concord would be looked at as something that a third party would make. (I don't even think it necessarily looks like something Sony would make, but it's not a big gap.)
I think people would be more interested, just because it looks so different from everything else they make; and perhaps wonder if Nintendo is expanding the kind of games they make (for good or bad).
Whereas with Concord currently, it looks like an arguably worse version of games that are already on the platform.
