Watch them enforce a proprietary storage device that is extremely overpriced sending the whole thing spiraling down into oblivion. Fingers crossed I'm wrong.
for that it would have to be priced somewhere in the ball park of the steam deck and offer more compute power than that. i don't see this from sony, i expect either a very expensive device marketed as as "premium" handheld or an iteration on their PlayStation Portal(?) streaming handheld.
Plus, they want to compete with the Switch. So it's not going to be good for any newer emulation. It is either going to be okay for a year or two and then struggle with its own games, like the current Switch or it's going to be DOA because Sony can't see and plan further than the tips of their fucking noses.
