Capcom has published a player survey for Dragon's Dogma 2. It asks for opinions on various aspects of the game, including what you like and dislike about it. But the most interesting question comes right at the end, which reads: "Would you be interested in purchasing DLC for Dragon's Dogma 2, if additional contents were to be released?"
Now, we're going to assume that Capcom is leaning more towards expansions here, rather than an additional offering of unnecessary microtransactions. After all, the original Dragon's Dogma was massively enhanced by the Dark Arisen expansion, which added a huge endgame dungeon to the experience. When people refer to the game as a cult classic, it's probably with Dark Arisen in mind.
So, if you want to see Dragon's Dogma 2 branch out in similar fashion, you might as well let Capcom know. You can find the survey through here, and it's open until the 21st April.
In the meantime, Capcom's already promised a slew of updates for the base release. The developer aims to improve the title's rather lacking technical performance, and implement graphics options.
