Actually the first sales and shipment of so-called Scrypt ASICS is sheduled to Aug 2014. Since it is the first date and they are now only in a development state, I guess it is a little early to start worring about them. Many chances they will be delayed in production.
More to say, until august in my opinion will be too many changes to coins, so scrypt-n coins likely to be replaced by something else more effective.
