Regarding playing simultaneously on 2 and 3 screens... based on my experience, I wouldn't recommend it. It's much harder to switch from 2 to 3 screens. It's much easier to play two games in parallel on 3 screens than in two different versions.
Most likely, there will be two such players - Horn and Dust. Both were planning to choose the dual setup... there are people who can replace them, we've already talked about it.
I could come from Kyiv for the dual setup. The most elite team is being assembled... but we'll have to make saves and provide detailed reports after the games.
