If you look at any coin on Cryptsy over the last month, 99% of them show the same downward trend.  The market glut of altcoins is finally reaching a reckoning.  It was inevitable.  When people were willing to invest in every new reward scheme, every new coin that claimed even one thing over other coins, no matter how irrelevant to its acceptance as a currency -- the dilution of all alt coins was guaranteed.  

Now with scrypt-Asics coming, most alt coins finish their death spiral.  There will be no new scrypt coins you can hop on to that can make you a profit as a gpu miner as one KNC will match the entire network of some dying coins or slow startups.  Only Doge and Litecoin will survive in the scrypt world.

So now we're seeing the the same thing repeat with Scrypt-N and Scrypt-Jane coins.  Since that's what GPU's can mine now.  Rinse repeat.  

Accept I don't think it will repeat this time, at least not with the GPU fueled ecstasy of the scrypt run.  People are more jaded, the trajectory of a coin after launch almost always goes down, and after 100's of scrypt coins just go to zero, I think less people will be willing to support some random coin with cloned features again.
