Sony was definitely able to build PlayStation into a consistent brand. People clearly understand that a PS5 is supposed to be more advanced than a PS4 which is supposed to be more advanced than a PS3, and so on. But Sony has more experience than either MS or Nintendo on thet front. You pretty much knew what you were going to get with a Walkman or a Trinitron.
Nintendo should have probably kept Nintendo Entertainment System/Famicom as a brand for its console line. Say "Ultra Famicom" or "Ultra NES" for the N64, as an example.
Microsoft was generally all over the place with their naming until Windows 7. Vista really came back to bite them. Windows 8 was so bad that they skipped pas 9 to 10.
