Visual Novels are still in the “catching on” process in the West. But if any company can make VNs popular here, it’d be Key.
Granted, I don’t really know many other VN companies with officially localized releases, the only one I can remember right off is Frontwing. 
Still, I feel that with proper advertising, LB could be even more popular than Clannad.
It’s a given that people like us who have played using the old English patch will buy it, so the main marketing target will be those who haven’t played it yet.
I just hope people won’t think “there’s an anime of it I can watch for free, so why should I spend money and 50+ hours on a visual novel?” Because as we know, there’s not much point in comparing the two.
