As a reminder, the PlayStation Portal, or Project Q, is (according to leaks) based on Android. It doesn’t run the games itself, it merely streams them from your PS5 and your handheld then serves as a controller with its own display.
I’m wondering why anyone would prefer that over simply using a regular Android phone with a good controller and the PS Remote Play app?
If this was PS5/PS4 streaming but with the ability to play PS3/2/1 games locally, it would kill for $200. And they wouldn’t fracture the PS5 development base, which they are obviously afraid of doing.
Hell, even some modern indie games that don’t use the full PS5 horsepower could have potentially make a PSPortal version for on-the-go gaming.
