Now that this has been around for a while, it's interesting to look at the results.
Skewb clearly wins. It's a pretty popular puzzle, it's a little harder than a 2x2x2, so it's not totally trivial, and I think there's a pretty good case for it. Considering past discussions with Ron, it seems logical that if we ever add another official event, it should be skewb.
Relays are second place. That surprises me. I've always thought it seems silly to do relays when the best person at the bigger cube will almost always win. However, I will admit that effect is not quite as strong for 2x2x2-4x4x4. Mainly I see relays as a pain to run and judge - you have to scramble 3 cubes, bring them to the competitor, and keep them all covered before starting inspection. Then you have to keep them all together as you bring them back to scramble for the next solve. I'd think it would be easy to get them mixed up. However, I guess it really went pretty well in the unofficial competition at US Nationals, so maybe my worries are unfounded.
The next 4 are all BLD events. Well, that is, if you count 2x2x2 BLD as a BLD event. It was interesting how the 2x2x2 BLD events came out at US Nationals. There were 12 competitors, and 10 of them got successes. I of course used my normal BLD method, and was beaten by 4 people, all of whom are awesome enough at 2x2x2 to easily beat me by one-looking a normal solve. (Thom could have done it too - I guess he just had a bad day.) It's pretty clear that people who are great at 2x2x2 speedsolve would dominate this event.
The next 3 BLD events are all ones I suspect the WCA would never support. I'm surprised by the popularity of 3x3x3 OH BLD. I suppose it wouldn't have to be that slow of an event, so it wouldn't be so impractical. But I admit I'm not a fan of OH speedsolving (it's my least favorite of the 19 currently official events, and yes, that even includes Magic!), so I guess I'm not a good person to be passing judgment on it. As for 6x6x6 BLD and 7x7x7 BLD, considering the people who already hate 5x5x5 BLD, I really doubt they could ever happen. (Sad, but true, and I'm a realist.)
