Everything they "announced" was already at least suspected thanks to what they put in strings in the last patch, but it's nice to hear that they're at least aware of some of the major issues like optimization. From the roadmap image...
New faction: Brit strings in patch
Optimization: Everyone knows performance is shit, but it's nice to know Relic agrees
Balance-focused support: Not really an announcement of anything
In-game store: Kind of an announcement, but still there's been talk of this since release and many of the strings in the last patch strongly suggested it
Better mod tools: Relic's been talking about this since mod tools were released, though user-created skins and "asset packs" are kind of announcements since the strings only hinted at user-created decals
User content and modding competitions: Something new that they never talked about, though you could've guessed based on their shift to user-generated content with all the strings about curation
Improved docs/resources: Again been talked about since mod tools were released
Leaderboards: Been talked about since the leaderboards here were created
ESL: Not exactly news since they didn't provide any specifics
In the end, talk is cheap, and this whole thing could very easily backfire if they take ages to deliver on some of these items. But the community seems more concerned with communication than actual content, so they're giving people communication. It's a little worrisome that the recent patch didn't provide anything to make the non-CoH2 player excited about picking up the game again, but maybe that'll change in the future. Or maybe Relic's happy with their player numbers right now and is more interested in maintaining rather than taking risks in the hopes of gaining more players. It's really impossible to know.
pretty sure they're working with UGC, not ESL, as UGC is listed on the road map and ESL is not. huge difference between the two.
UGC is user-generated content. It's not a league or a tournament. UGC curation literally means taking user-generated content on the workshop and incorporating it into the actual game. User-generated content has nothing to do with ESL, which was also shown on the timeline image.
