I voted no, because Switch is a rival and will sell more.
That said, I think PS5 will do well. As the launch of the PS4 proved, the some fans of the PS-brand will buy the console purely on brand power, even if it is missing games and mostly has remasters. But the brand-expectation is, that the PS-platform will eventually deliver and they eventually did. So I see no reason why this gen the fans should have another assumption.
