Some interesting info for late 2016-2017 posted:
Next year, air superiority jets will fight for control over our simulated skies. More details are forthcoming but, for now, we can confirm this package will be supported by a free platform update, with radar / sensor improvements as its stand-out feature. By adding more depth to threat detection and tracking, we aim to improve gameplay across the entire sandbox.
We round off this roadmap with an ambitious goal: overhauling the experience of armoured combat in Arma 3. This package will follow our well-established model: a set of premium assets, which bring something new to the sandbox, supported by platform improvements and additions for everyone, for free. We encourage our community to share their own wishes on the topic, too!
