And even from just reactions in this thread it seems to be working. I dont understand what is so expensive - die shrink or more mature production means larger APU is possible at similar cost. PS4 pro is more than double the performance of PS4 but at the same price as launch. Scorpio is about 50% more, 12 months later. I can totally see it being in the ballpark of $399.
Only wildcard I can see is if they go for separate CPU/GPU rather than an APU (maybe apu would be too big?). That could increase costs and allow them to go with zen for CPU. But I don't know how that would affect BC
Isn't scorpio supposed to be almost 5 x more powerful than the original. 4 years later, 5 x more power, 12gigs of GDDR5, still likely has ESRAM (or perhaps it doesn't thus creating a compatibility headache) amongst other improvements. A realistic approach would be to expect a price north of $499 unless a loss is involved. Fabrication costs go up quite considerably depending on the size of each chip and it's unlikely the scorpio APU will be the same size as the original's.
