I.e can Ethereum mining be profitable for the next 12 months or are any of the other coins gonna need mining that is doable by cards,  for at least 12 months ..

I highly doubt it. With the difficulty bombs continuing to drive Ethereum difficulties ever higher, and with continued network hash rate coming online daily, it will not be too long before those with higher power costs barely break even much less worry about ROI on any recent hardware purchases. Even if you switch to a more profitable coin it will not be long before others do the same and drive that coins mining profitability into the ground as well.

Rinse and repeat this a few iterations through all the somewhat profitable-to-mine coins and soon GPU mining will soon be a thing of the past. Don't count on Ethereum's future update to come to the rescue either, although it does reduce difficulty the block reward will also go down from 5 to 3 ETH making mining profits about the same and even a bit lower than they are currently.

Soon only those with sub $0.05 power cost will even be able to turn a few pennies profit. I predict a lot of used GPUs on sale for this coming Christmas, which should also pressure the prices of new GPUs to come down as well. Gamer's will finally be happy again!

that 5 to 3 block reward is freaking lame ,  ill mine etc

All the cards I'm adding are used cards at a steep discount off of Craigslist that I plan on just running into the ground.  The prices around here new are still really inflated. 

Not in a long time, on normal ethereum at least, considering the least expensive 4GB RX card is the 560, which is $150 dollars, it would take almost 5 months to regain your money.
Maybe you'd be better suited with Monero or another newer coin with potential, maybe ETC? Only big rigs with cheap electricity can generate a fair amount of income nowadays.
