I wish I could take a picture of my forum feed, every post is ETH being dumped followed by ETH Soaring! 
The ETC pumpers will claim the ETH dumps and the ETC dumps will speak out the ETH pumps. So it depends on which one you like.
I have sold out all my ETC in the last few weeks. As I believe that the ETC dump will come out very soon, maybe in the next 4 weeks.
etc will be pumped when eth will go pos, because miner will pump that to attract new investors, for their profit, the old fork instead i don't think will increase much more will remain there like any other pos coin, stagnating without an end
But for now there is no news about eth that they will convert into POS.
If the Ethereum goes into PoS, the miners will not support it, so the community will be smaller and price will drop.
I think the opposite. Right now most of the so called miner's support consists of mining the coin and selling it right away to recoup costs and secure some ROI. It is this reality that is keeping the selling pressure on ETH and the price down.
After POS hits, mining costs will be a fraction of what they are now in terms of electrical costs, so the incentive to hold longer will become greater. Once miners are not dumping daily, the price will tend to rise assuming the same level of demand. Most of the miners you feel are part of the community will move on to mine another coin. So even if this part of the community gets smaller, it is not like miners are buying their own coins to begin with, so this should not cause anything but positive upward pressure on price.
Similar thing happened with Bitcoin, although in a different way since Bitcoin is still PoW, in that once the mining moved out of the basement's of people who mined and dumped and into larger more professionally run farms the price began to rise. These profession farms are managed and located in a way in which maximum efficiency is obtained at the lowest costs, so the pressure to sell at a slight profit is less.
The cost of mining will put a floor price on the Etheruem. For the PoS, there is little cost, so people can sell cheaply.
