Please note that did not happen with previous hashrate jumps. Now the impact is much less because of larger coinbase and lower reward.
Also in you diagram the most additional coins are generated right now. the price did not drop today.
Previous hashrate jumps were caused by price increases,
not new technology. That said, I don't believe ASICs will drop the price any more than psychologically.
lol. I was not here myself back then but word is when GPUs came one person got more than half of all the blocks for weeks if not months.
Remember that increased profits means inflation, so if miners do earn more money there will be more inflation. However, mining is such a small part of the economy (~2%) that this isn't likely to matter.

would be interesting to look at all the past blocks and make a filtered chart of the coins found.
http://blockexplorer.com/q / nethash/2016 should be enough to do it.
