Taken from your review.
"Scrypt coins, especially Litecoin, were originally developed so that anyone with a computer and programming skills could mine them, unlike Bitcoin mining, which now can only be done with highly specialized and powerful Bitcoin mining hardware. However recently application specific integrated circuits (ASICs) have been developed for scrypt mining, which means that within a few months scrypt mining is likely to have its own version of the exponential rise in Bitcoin mining difficulty. This is likely to reduce scrypt mining rewards in the near future, especially once scrypt mining hardware becomes available to the general public."
Scrypt ASICs are already out (Gridseed) and many coins are moving away from pure scrypt. (scrypt-N & scrypt-Jane for example) The ASICs can't follow and have to be redesigned before they can impact those coins. It is beginning to look like maybe only Litecoin and Doge will stick with scrypt, although there will probably be some short term coins like BC, WC and AC that also use scrypt. While you are right that scrypt ASICs will push the difficultly up for the coins that can be mined with it, it is unlikely to make a big dent in altcoin mining.
A few months ago, people were saying there wouldn't be in profit in a few months and it is always a few months. GPUs are flexible, ASICs aren't. The only coins that will be impacted are the ones that choose to be impacted. I don't think it should be considered a major factor.
