For SCRYPT Coins GPUs are better

ASiCs can only mine SHA256d Coins not SCRYPT Coins

Litecoin / Feathercoin / And Countless Others are all SCRYPT Coins and CAN NOT be mined with ASiCs

While up to fairly recently that was true, there are new ASICs coming on the market that would allow for mining scrypt, but they are slow and expensive. (approx. the cost of GPUs, though they do take less power to run.) As with all emerging technology, I expect the price to drop and the power to increase very quickly, but still as a proof of concept they do exist and are currently being prototyped/tested/reviewed all over the place.

I am curious what they will do to the litecoin/bitcoin exchange rate once they are in full-scale deployment like the current sha256 ones.

Yes they do I know this but Yes , They are not cost effective nor are any of the units actually in stock anywhere. The main chip powering them is the Gridchip GC3355 made by Gridseed @ http://www.gridseed.com/
