I expect it will revert, but what I cannot predict is when the reversion will occur.
Why:
1) Eventually another "AI Winter" [1] is going to occur (again, no way to predict when). But the current hype cycle and endless money burn with no visible path to profitability is going to catch up to all of the AI's and an AI Winter will occur. When that happens, the AI demand for RAM/GPU's will crater (and, as well, some portion of the existing purchases will be sold off at bankruptcy discounts). Both will result in a reversion in pricing when the winter arrives.
2) The current extreme pricing will also encourage one or both of:
2a) existing players to ramp up their production capacity to meet the demand; (this will be sluggish, but as they begin to ramp up their capacity, the result will be a softening of prices)
2b) the high prices may encourage other players to enter the production market to capture some of the current profits, this will also soften pricing;
Once the current demand spike calms down (and it will calm down) both 2a and 2b will lead to a reversion in pricing.
What I can't tell you is how long we may have to wait for the reversion. It is coming, sometime in the future, but how long we have to suffer the current extreme pricing before it arrives we can't predict.

So, more chips coming soon, but who knows if that's enough to keep up with demand for the next few years.
With the past investments of Nvidia into openai, the business model held up. Lately, AMD has caught up enough in AI efficiency that openai decided to built an entire stack of servers in AMD. openai's boyfriend i.e Nvidia did not like that and with Nvidia unable to guarantee return of investments via sales of it's cards to openai, Jensen Huang i.e. CEO of Nvidia is backing off from investing 100B$ simultaneously tanking a -6% of stock in a week.
DDR6 will be bigger and better but not cheaper.
