RTS tournaments tend to revolve around 1v1 gameplay, but your more than welcome to enter them under the ATK or the new name. The only one that I can think of that isn't 1v1 is World In Conflict, but only I have that, and no-one else seems keen to buy it. This is why I haven't put them in as a possible selection. We may form a 'training group' for the better players of these games to hone skills against each other, and run small ladders, but nothing as well organised as a team at the moment.

Looks like DP/DE and the unappointed CS leader will have quite a pool to pick their team from.
