My reasons for wanting this aren't related to the actual game holding up (or not) against others.
The main reason I brought this up some weeks ago was because they seem to be taking care of two separate games ever since the launch of the console versions, and they were never able to catch up and reverse this. The idea that comes out is that it's one big mess and a waste of time, to the point where Stefano sometimes just doesn't know what's happening in the console versions. I see that as a waste of resources and a recipe for (more) disasters. And as such, launching a new game, made from scratch and for all platforms sounds like something that would make sense. And quickly.
The other reason (directly related to the above) is: what are they living off right now? I'm pretty sure sales of AC are residual nowadays and that $8 DLC now and then won't cut it. Shouldn't they be deep in the development for the successor, to grant the launch of a new game in a near future? What was the consoles version for, if not an investment to make some extra money and use it to grow the company and take it to the next level?
And even for PC users (as discussed at the time and once again above) it's clear they want to move on to something more modern and fresh.
Keeping AC running and adding stuff to it seems (to me) like a waste of resources, for the reasons mentioned above.
