I've been reading all these comments, and it's honestly quite interesting (and cool) how passionate people are about cubing!
Now I don't a whole lot of room to talk, as I've never been to a comp before, and have only been cubing for about 7-8 months, but as efattah said above: "The people with more money, and the better eye for media & sponsorship always win in the end, if they execute well." There is a reason why Monster Energy now is NASCAR's main sponsor; they have the money, and they want to make more of it.
If you think about it, this could give cubing a new look, which isn't inherently a bad thing. However, as the old saying goes: "If it ain't broke, don't fix it." The community is fantastic right now (from my perspective), and there's nothing about that seems to need change.
One thing that I haven't seen is the fact that competition (in terms of Rubik's vs. WCA) ALWAYS leads to improvement. The fact is, if Rubik's competitions are better than WCA competitions, then people will leave the WCA for Rubik's; that is basic economics. However, it might be such a thing that nobody likes the new style of comps, and then Rubik's will fail colossally!
This doesn't mean cubing will suck now; it's just a part of change, and the I guess the best thing to do is to take it with our best foot forward, because who knows? It might be one of the best things that has ever happened to cubing!
