Doesnt seem so. this just reveals what the placeholders for DLC would be. So as long as they go with the same plan that the proposed in the placeholder files, this is going to be the eventual product.
I think judging based off of how much DLC they did for attila, that we will see 3 more MAJOR DLC packs before the end of the year. Maybe one in July, one in september, one in November. I know that theres gonna be a lot of FLC coming out like new legendary lords, new magic lores, etc.
