Wait, what? That isn't how I read his posts. If Sony decided they wanted more power and lets say as an example they were ~8TF for a 2019 launch and chose to delay to 2020 for 12TF, then it would require a complete from scratch redesign of the entire system (as Albert explained) and that won't happen in anywhere close to a year. It would be tweaks in a ~12 month time frame.
I can see how both interpretations would seem in conflict.
To be clear (and I have no insight into Sony's plans) I did say it's unlikely they would delay from 2019 to 2020 and ship the same product. The only reason to delay a year and ship the same thing would be for better yields/costs - but in reality if they thought they could get a head-start on Xbox that would FAR outweigh the benefits of the cost improvements.
And I did say you could make some changes last minute - the PS4 upgrade to 8gb was pretty late in the game (less than a year before launch IIRC) and that's very plausible to me.
You also have to assume some level of delay between when Sony planned to do something, and when rumors start to spread publicly. So it's conceivable to me that, by pushing out a full year (if that's even true), you could make changes.
Also - why do people assume the change was to upgrade? Maybe they intended to do ALL the Tflops, figured out it was going to be much too expensive, and downgraded.
Point is, we don't know when, or if, they decided to delay. So the changes could be major, they could be minor. They could plan to upgrade, they could plan to downgrade. Only they know.
My bet is that if it's even true they did delay a year, it's like to mean a change of some sort.
