I feel the same, I don't really trust gearbox, so I'm cautiously optimistic. Hopefully it was a case of Hopoo trusting gear box after their long partnership, and not a case of Hopoo looking to make cash with the sale of Risk of Rain.
consoles will get dlc content today for the anniversary. I think they'll only announce the dlc properly, and let people play with Risk of Rain Returns for a while before releasing the DLC. it would be bad marketing strategy to split the community between two game
Every few months when I'd check for any word of anything on RoR2 the internet always said that all efforts were focused on Risk of Rain Returns. So to hear they're also working on more content for 2 is a welcome surprise
