I may be confused about the whole x11,x13,15 scrypt miners, but I think this could be the death of altcoins. The value of coins could plummet when these things are released. If I'm wrong, please someone explain!
Whoever gets the rigs first will make a fortune
nope. Eventually everything will even out as everyone will have the same rigs and the difficulties will adjust upwards accordingly. The more rigs you have the more coins you will mine.
Eventually EVERYONE who mines will need to have these rigs to stay in the game and remain competitive.
Seems like BOOM and HASH are a great buy right now

Those rigs won't pay for themselves cause x11 x13 x15 coins will go up in difficulty so much, that they wont make enough to pay for the electricity ( even though small ) so the one making money are the ones selling them. Look at the asic scrypt miners, they didn't pay for them selves , the scrypt coins cant be mined with profit now, so now it will be x11 x13 x15 ect. look at nicehash scrypt before the big sale of 28nm technology .6 to .9 btc gh/day now .3
