That's odd. When you look at the top players of Brawl, you'll notice that a lot of them don't even own wii's. Ha!
Smash players play smash because it's fun as hell and the community is the hypest by far.
How so?
Edit: I can see how since L-Canceling was removed, and buffering was added, you can say they removed a lot of the technical skill involved, but that really isn't true. Playing frame perfect is a very important part of smash.
It's really more in-depth than people give it credit for. So much so, that when people coming into the game look at it all they see is "Broken", when little do they know EVERYTHING in the game can be punished at top level play.
