The format that we would like to propose is similar to one to be used for MW2 Knockout which looks like this;
Winner of Group C vs 2nd of Group D = Winner Match A
Winner of Group A vs 2nd of Group B = Winner Match B
Winner of Group B vs 2nd of Group A = Winner Match C
Winner of Group D vs 2nd of Group C = Winner Match D
This is still subject to agreement from other officials, which we will confirm again on the spot later today. But for now this what you can expect later.
The only possible difference should a disagreement arise would it to be A v C, B v D instead.
