maybe they will soon be at saturation and will release chips, finally?
While this is an interesting thing to consider, it seems to be pretty speculative to conclude that they will actually do anything regarding chip sales. When/If/How they sell chips and miners get built seems way longer term and unrelated to how much the network hash rate they seem to have over a 24 hour period.
As suchmoon said, many days would be more accurate, though still speculative in terms of chip sales.
