25M Sell-in is too low when IDG have 81M for PS5+XBS Sell-through at the end of 2023.Yup, I too think these estimates are on the optimistic end.
Ampere's 2023 estimate was made before the collapse of Xbox in the 2023 holidays, it was even before the November NPDs.
Also feel like Ampere is overestimating the amount of XBS sold outside US/UK. Their ratio of sales versus what we have from NPD/UK GFK gives a ratio of 0.54 in 2023, which again is before they knew about the full holiday collapse.
For reference XB1 is ~60%+ US+UK versus total shipments.
So Ampere had XBS at 27.1M end of 2023, I estimate it as 25M. This is sell in.
2023 Shipment is likely just 1M extra (low demand, even PS has lower channel buffers versus last gen) so 26M by end of 2023.
1.7-8M shipped so far in 2024 gives me a LTD rounded as 28M.
With ratio % errors and shipment leeway, I think 28-30M is the final shipment range at the end of Jun 2024.
81M - <55M = >26M.
If anything it's most likely that IDG and Ampere were undertracking Xbox.
Previous IDG estimate for EoY 2023 was this:
77M - <55M = >22M.
The main effect of IDG upward revision was to increase Xbox Series floor since with PS5 55M is in both case the absolute maximum given Sony Sell-in numbers.
The last time Ampere made a revision regarding to Xbox was to updrade total sell-through from 18.5M at the end of 2022 to 19.5M.
IDG and Ampere would not upgrade their numbers without data showing that they were previously undertracking consoles sales.
