I doubt they're going to work on the Affinity suite much more, it was probably more of an acquihire, where they'll get the engineers to work on the main Canva product.
I've used Affinity for years, it was pretty much in a feature freeze state before V2 (which didn't really add anything major). I'm fine with that, it's more capable and user friendly than GIMP and Inkscape so I was happy to pay for it.
> 1. We are committed to fair, transparent and affordable pricing, including the perpetual licenses that have made Affinity special.

If we should trust that or not is another matter. I’m inclined not to.
