No way to know it's dynamic and based on demand.
EIP-1559 effectively doubles the Ethereum block space, but then it targets blocks only to be 50% full.
When Ethereum blocks get more than 50% full, the gas costs for inclusion will increase. When blocks get to less than 50% full, the gas costs decrease.
The change in gas price is not linear, it follows a curve and gets exponentially more expensive or cheaper the more blocks in a row that are below or above the target. Read the spec for exact details.
Adding sharding will increase the amount of block space that exists, but that will also increase demand. Read up on Induced Demand to learn more about this concept.
This is also a self-regulating mechanism. If the network is saturated, then ETH is deflationary and gas will be expensive, which is an incentive not to spend it which should decrease saturation. If the network is not saturated, then ETH is inflationary and gas will be cheap which is an incentive to spend it which should increase saturation.
