If true, it means both configurations are within spitting distance of Valve’s comparative pricingwhere a 256 GB Steam Deck costs $530 and a 512 GB Steam Deck costs $650, respectively. But Valve also sells a $399 Steam Deck that comes with 64 GB of eMMC storage, which enthusiasts often open to get that SSD to replace.
The original ROG Ally leak came from Best Buy and it seems that Best Buy is also the source of this. This will probably be the least expensive configuration of the ROG Ally, although it’s possible that Asus could follow Valve’s lead and release an eMMC model.
Update: Added confirmation from Roland Quandt, who believes he has the same source as SnoopyTech for this data.
