Today's Update was the first time(at least for me) that showed a Yellow-bladed Lightsaber. Looks cool, and something about it got me thinking.
That blade looks much wider than the others. Are blade width, lenght, and whatnot customizable? I'm going out on a leg here and making sure i've not missed this little info, because otherwise it would be NDA breaking.
