Cuphead was spotted on the PS Store’s featured page earlier today, which might be someone hitting the publish button a tad ahead of time.
Many users spotted the promotion, including Wario64, who said that the game listing doesn’t load yet. This means the game is pretty close to being released, and with a special update from an indie studio happening this afternoon on the Summer Game Fest, (5 pm) it seems highly likely that the official news will appear in that slot.
Cuphead was an Xbox One and PC exclusive in 2017, before making its way over to the Nintendo Switch last year.
If there is an announcement from Canadian developers StudioMDHR, hopefully there will be news about the Delicious Last Course DLC for Cuphead. The DLC was delayed until 2020 last year in July, with very little information about progress since then. A full year without an update is a fairly long time.
