For some it probably will, but it depends on what the price does in the months leading up to it. If there is a sudden increase in price prior to the event, then everybody will still be profitable, like right now. But everybody doesn't have the same profit margins, so if rewards are lower, then the least profitable miners will shut down their rigs. That will make block generation slower for a while, until the next one or two difficulty adjustments.

It doesn't, it adapts every 2016 blocks. Because the general price trend has been pointing upwards, and there is a lag between the decision to invest in mining infrastructure and actually contributing hashes to the network, the adjustment is almost always to make it more difficult.
