I think the comeback that anyone has ever been talking about was never about profits, except for opposing people.
I definitely agree that PS3 made a huge dent in profits when it launched but just to be devil's advocate because you are missing a lot of things.
When did PSP become profitable? It launched in Europe late 2005 and vita is taking 3 years to become profitable. Easily a billion or 2 in losses from the PSP nobody knows though.
Vita has been selling terribly for all of its life. PS3 profits could have been upward to 1 billion or 2 but vita losses minimized that.
Then in the last 4 years their was PS4 R&D. Another billion or two. So really your numbers are not accurate enough to prove anything.
