Asics are starting to and will soon obliterate scrypt.
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.

The Gridseed ASICs that can mine scrypt have been on the market for a few months already and there are multiple group buys on this forum, web stores to buy them, and tons of photos and threads for them in this forum.
Here are some photos of them:

In fact, there are quite a few people who've been using farms of these Gridseeds on Clevermining and Wafflepool and have posted here about it multiple times, including overclocking tips and setting up BFGMiner with them.
