I am sure at some point in time far in the future a bitcoin clone will fork with some inflation. Whether people follow the fork and the  almost certain lowering of value inflation would create is unknown. If transaction fees are too low, AND no one wants to mine the original  btc chain at a loss / voluntarily, AND those with a great financial interest in the main chain thriving don't want subside mining at a loss as a cost of business, then maybe a majority will move over to the forked btc+inflation coin. Far. far far in the future though.
