In an interview with Gamepressure.com, Obsidian Entertainment CEO Feargus Urquhart reveals the company is currently developing Pillars of Eternity II, a sequel to their crowdfunded RPG. He seems to make a distinction between acknowledging and announcing the game, but confirms that it is actually a thing, and that they are probably going to turn once again to crowdfunding to complete the project:

However, they’re most probably going to turn to Kickstarter to crowdfund Pillars of Eternity II, and that’s when Feargus shared what they’re currently involved in:

Obviously, as you’ve probably guessed, we’re starting to move forward on [Pillars of] Eternity II. That is probably something that we want to look at [in terms of crowdfunding]. I think people felt like we delivered on our promise, and then that felt like we could go with Eternity II and people would support us again, because they trust us.

When we asked him about an official announcement of Pillars of Eternity II, that’s what he had to say:

Eternity II is not announced, [but] it seems silly for me not to acknowledge it, though. If someone asks: “Are you working on it?”, I respond: “Well, wouldn’t you work on it?”. So then they say: “So you must be working on it”, and then I’m like: “Well, yeah”.
