Yeah, I was hoping for a patch this week but like others I'd rather have a game that lives up to the BG2 legacy than one that is rushed out. I'm fine with 2 years or more.
I hope it's two years. It needs time. It might be "good" if it released soon, but it would be a damn shame if its potential of "Game of the Decade" was to be squandered.
I think it would be optimal to have a big patch roughly every month, with alternating "new content" (races, classes etc.) and "mechanical changes" (6-slot party, closer to 5e) patches. Some hotfixes in-between. That after they deal with the EA-release-related backlog, of course.
