Maybe this has already been addressed in the posts following, but Nintendo's methodology in the last couple years on forecast is the following.
Q4 Results: Set Forecast (25.5M)
Q1 Results: No Change
Q2 Results: Change based on H1 performance. So in this case, H1 underperformed by ~1.5M.
Q3 Results: Change based on Q3 performance.
So what we now know. Forecast was originally 9.5 - 10.0M H1 / 16.0M H2. You can apply the same logic to last FY;
link - pre-Q3 results << following that when Q3 results did come out, they increased the presented forecast further by Q3's outperformance.
I agree with Stu. Their 16M Q3/Q4 forecast this year is a long shot given supply issues. They already missed H1 by 17%. I think they were expecting 5.0M / 5.0M / 10.5M / 5.0M quarterly, and haven't been able to meet target yet at all. I know demand in JP pre-OLED was down but I think this is mostly a production issue caused by the supply-chain.
