Yes,but you'd expect the price to increase proportionally with the reduction in block rewards, However it would be nonsense to imagine an instantaneous 72x increase in price, Seems that it would be prudent as a miner and supporter of the coin to start sliding down your votes as the sustain phase approaches to create a smooth transition.
Exactly, we need/have to go from 582 to 8 HVC reward in approximately 90 days time with a proportional increase in value to offset the difficulty and still keep the coin slightly profitable to mine. It's possible to do but each and every day the votes stay high just makes it harder and harder to accomplish. Right now the current vote is approximately the same as when it started or roughly in the middle. If this doesn't change then we'll have the cliff on the 1st day of sustain.
I am a HVC supporter and investor but I absolutely agree with Carlos on this one. Having a huge reward cliff like that is really dangerous for the coin. There might be small chance that the coin will survive it but it would be much safer and healthier to start voting the rewards down gradually.
As most miners seem to be too stupid or greedy to realize this we would need some sort of community initiative to reward low votes. One example could be a pool that gives out extra rewards for blockfinders with a low vote. This could be subsidized by the community with donations for example.
