The Mario edition OLED should give Switch aboost before the game itself arrives; things should be pretty chill til then, albiet with a baseline that remains truly impressive for a system so old.

Pikmin 4's legs really are something, finally releasing on a successful console has worked wonders for the series.

XS reaches 100K YTD and potentially 500K LTD next week

We are now at a point where a game like One Piece debuts 4x higher on the Switch than the PS4. And Armored Core has sold over twice the total amount on the PS5 compared to the PS4. I realize that PS4 games will keep coming for a little while, but the PS4 versions are really at the "why even bother" point of sales.

Did only the Switch verison of Bomberman get a physical release? PS4/5 got copies here in the West, but in Japan, 11k on Switch but no PS version on the charts with a 1261 copies cutoff point.
Makes sense if not, since Nintendo gamers seem to value physical more and given how physical games sell on PS in Japan, there may simply not have been enough demand for one.

Online Japanese stores are selling PS4 and PS5 versions of Bomberman R2 so I'm assuming that you can find them in physical stores too.

It'd be reasonable to think that since the first Bomberman game on Switch was exclusive for a while, most of it's selling was therefore on the Switch platform meaning, it could've cannibalized the community to its platform

A mistake on the row of the PS4: last year to date 651 vs 54000 this year?

No, that are the correct numbers. Last year the PS4 had no stock at all. At the start of this year they restarted production it seems.
