The last ETA (of "some months") was from mid-March, but there will be more information announced soon. A teaser was posted on Facebook and Instagram, and it was already stated information about the next projects would be revealed at E3, so that leaves the next update and Linux version.

Dragon's scale and witch's hair,
Take a peek soon, if you dare.
Tooth of wolf and impish blood,
Something wicked this way comes... #divinity #originalsin #larianstudios

"total lack of info"? If calls for new updates started a week after the last update (minor complaints immediately, of course), 2 weeks later it was completely outdated, and 2 months later it doesn't even exist, is it surprising that Larian would rather focus on actually working on the update than posting progress reports (which would still get criticized anyway)?
