LotR LCG in it's current form to end mid 2020; new kind of content to follow after some period of a break, no "2.0" kind of release as it feels unnecessary
aGoT LCG will finish current cycle, Targaryen faction box and some kind of special release to be announced soon which will mark end of cycles. Content will continue in some new kind of format with much slower release. Feel like they can't do much more with the game, mostly because no new books
Arkham Horror LCG doing extremely well, no plans to change anything
No plans for new Netrunner LCG
Journeys in Middle Earth has a planned finite amount of planned content; will deviate from Mansions of Madness release style with only doing figure packs and big box expansions, no small box ones.
Eldritch Horror is a completed game (no new content will be released)
Elder Sign is a completed game (no new content will be released)
Descent is a completed game (no new physical content will be released). Hinted at something coming up, possibly a 3rd edition
Imperial Assault is a completed game (no new physical content will be released); "business reasons" is answer for why no new content (reading between the lines = cannibalizes Legion sales); more digital content to continue
Runewars will not be getting a new version or re-release
New Tannhauser content: often discussed but cannot provide any info
Runebound is also a completed game.
Heroes of Terrinoth's future support is unclear.
Fallout getting a new expansion.
