[Monty Python]

It does appear as if the gate is in the middle of the field and while I can definitely see FIRST doing something unpredictable and changing up the alliance structure, my gut feeling is that they won't (not basing this off of anything, it just seems unlikely to me). So to me, the question becomes why bother moving the gate? My guess would be because human players have to stand in that area. If human players are standing on one side of the field, they can't be symmetrical across the field and there could be some competitive advantage for either side (obviously FIRST wouldn't want an inherently unfair game). This leads me to believe that human players will have limited importance this year and, for instance, will play a role more akin to their role in Stack Attack as opposed to their incredibly important role in Lunacy.
