In the leaked info, we know that Valve has an upcoming device that will use the same APU as the current Steam Deck. We don't know if this will be a new VR headset or a Steam Deck hardware refresh. Even though using the same APU means there won't be a performance increase, there could be various other improvements in an upgraded Deck like a better screen, etc. What would you like to see in a partial hardware upgrade?
Unpopular opinion but I'd rather see wider worldwide availability before having a hardware refresh. Getting more Decks out there should be on top of the list before trying to sell upgrades, specially when the current deck does so much already.
