Adaptive sync is what the monitor scalers will support as part of the DisplayPort 1.2a spec. FreeSync is AMD's hardware - driver support for adaptive sync. Nvidia is free to support adaptive sync in their drivers if their hardware is capable of the spec in full. AMD would clearly only discuss that AMD cards will support adaptive sync via FreeSync since they have no responsibility for whether Nvidia is able / willing to support adaptive sync as well, but they have mentioned that being part of the spec means that graphics vendors are able to support it (without any costs related to AMD in any way).

That makes sense, and I do understand. Yet I don't really see nvidia going for adaptive sync since they will want to milk the gsync cow for sometime longer. That's why I am thinking, there won't be any freesync support in geforce drivers, and probably no adaption of adaptive sync, or do I understand the things happening there wrong? I'm just considering buying a new monitor during the next months, that's why I am starting to look into the matter of gsync and probably competition to the ROG swift from asus...
