Hopefully the "future of speedcubing" (mainly 3x3) does not necessarily become the "future of CFOP", which it seems to be becoming. I don't think any other method has been explored nearly as much as they should be. After people learn LBL, all I really imagine currently happening is young kids typing "Rubik's cube World Record" into the Youtube search query, seeing Faz's videos (and calling the method Fridrich, which is still "correct" by popular agreement, although CFOP is more precise), and thinking that his method is the fastest and best there is. The similarities between LBL and CFOP makes it an easier transition than from LBL to Roux or Petrus or any other method. What if someone actually took Rouz or ZZ took its limits and found that it is faster than what CFOP currently is, although by a matter of hundredths of a second on average, or case recognition or whatever it may be?
In short, I don't know much about the future competitive speedcubing, and I totally agree with Chris Hardwick's first post in this thread, too. No one knows what the future will be, but we can certainly take a guess. However, I for one desire a more diverse speedcubing community(in terms of what methods cubers use), since it's already pretty obvious that it's growing. Maybe we'll be surprised by what we find when we see people take a deeper look into different methods, techniques, theories, etc.
Since it is impossible to try to foresee the future, we should focus some of our efforts in trying to direct the future. To help diversify the community, and to direct newcomers (newbs), it would be cool if we had some type of "Featured Method of the Week" sort of thing on the Home page of these forums. For example, one week it could be Petrus, and it could give a short history of how it started, its origins, notable users of the method, or simply a redirect to the Wiki page for that method. This shouldn't be limited to just 3x3 methods, but to BLD, 4x4 K4, Gigaminx, Pyraminx, Clock, etc. (sorry if it's not applicable to some of these puzzles, which I'm not familar with, but I'm guessing they might be). That way, newcomers will get a small peek at some other method before they take the plunge and commit to CFOP or some other more popular method.
We should not be afraid of the words "intuitive" or "blockbuilding". Just an idea and some thoughts.
