Inventory situation (G&NS=PlayStation):
Inventory situation when PS4 was as old as PS5:
During normal times Q2 was the typical peak (to get stock for the all-important holiday quarter), then the level tended to more than halve after the holiday quarter has concluded and to decline further in the Jun-Mar quarter (save rare occasions of strong unmatched demand after the holidays).
PS5 went through a special period of high demand/relatively low production capabilities triggered by the pandemic that made unclear how much demand there really was for PS5 (sky was the limit cause production couldn't catch up).
Then in the second half of 2022 normalization began, inventory uncharacteristically kept growing even after FYQ3 and FYQ4 but that was fine because SIE was playing catch up with past unmet demand.
Therefore they went ahead in projecting a historical fiscal year for the current one and inventory kept growing until FYQ2 until reaching a record level then came the holiday quarter with high expecation but demand got normalized during the fiscal year and sales were "lower-than-expected".
After FYQ3 inventory remained at a much higher level compared FYQ2 than typical for a normalized period (about two-thirds).
