I'll ignore the other debate that's going on at the moment and just point out one thing.  If Samsung are merely producing the hardware for sale and not actually using it themselves to mine, they're not going to care in the slightest what the difficulty is.  And providing they manage to sell lots of their hardware, they're likely going to make a profit whatever happens to the difficulty.  The only people in this scenario who would potentially face huge losses are the miners whose hardware isn't up to spec anymore, along with anyone who tries to sell ASICs that aren't up to spec anymore.  Obviously this all assumes Samsung do actually make decent mining rigs, but we'll have to wait and see to know that for sure.
