I am actually thinking that it has this potential. There are more factors than ever going for it. For one, they have more fans than they'd ever had. The documentary has nearly a million view on youtube and it really hasn't been out that long. Second, they've got one of the most talented drummers in the world (and all the "drama" and attention that has accompanied it. Third, Roadrunner has, to my knowledge, become the main label for the metal scene. Fourth, we have sort of entered a "Rock Band" culture where instrumental skill has become something people have started to cherish.
I think the time is better than any other (except perhaps the time period around IAW) for them to make it big.
