They say there will be surprises in store for those that participate, at least thats how I'm reading it. http://forums.station.sony.com/ps2/...est-indar-4-20-19-00-utc-noon-pacific.118089/
Looks like the surprise was an appearance by the new buggy. Turns out the new buggy is a bit... buggy. Therefor, it didn't make the planned surprise appearance.
