Hm, you just never know. It was just opinion, though. But it'll seem pretty stupid if they did ban shinies from official tournaments. In all honesty, it just seemed likely because a lot of people would have them and everything.
On a side note, I'm exactly 105 Pokemon away from completing the national dex on Black 2 to get the shiny charm. Half of them I don't even know or bother trying to go find, lol. This doesn't include Keldeo and Meloetta.
Anyway, I still think this is good for those who can't seem to run into shinies at all.
