As Luke3161 said in post #347, everyone is postulating games that are too complex. You have to consider that every piece needs to be constructed for the regionals, so expense really is an issue. In addition, the GDC will be thinking about teams that do not have a ton of money to blow on replicating a super complex field. And has been said several times, I think many teams, rookie and veteran, would have a difficult time producing an entirely new form of drive train. Most teams just do not have access to the resources necessary to build walking robots, especially as many have invested so much in making ones based on wheels.
However, I do think the Locomotion (as a name) and mirroring are probably some of the best ideas so far.
